It can’t always be easy having Madonna for a mother, but it sure does have its perks. Madonna and her 13-year-old daughter, Lourdes Leon, are collaborating on a new clothing line for Macy’s. The teen collection will be called “Material Girl,” and Madge says Lourdes is doing most of the work. She told Us Weekly that after her work for H&M, she didn’t have the energy to do an entire adult line by herself. Working with Lourdes, she says, gives her the freedom she needs to focus on her other careers as well. Madonna claims that though she’s certainly involved, “Lola's really doing the work. I just sit in the corner on my BlackBerry!” Lourdes has the benefit of growing up around fashion, according to Madonna. “She also comes to my photo and video shoots, pulls outfits together and gives her input to a lot of my fashion-designer friends,” the icon says. “Whether it’s Marc Jacobs or Stella McCartney, they always ask her what she thinks.” Stephen Lovekin / Getty Images for The Weinstein Company Lloyd Bridges’ three-year run as Captain Mike Nelson on Sea Hunt earned him his own CBS drama, The Lloyd Bridges Show in 1962, produced by Aaron Spelling. Sea Hunt lasted just 34 episodes, but it did feature appearances by his two sons, then-21-year-old Beau and 13-year-old Jeff. It was the first of many times the three would appear on screen together. Over two decades later, they were all in Tucker: The Man and His Dream, 1994’s Blown Away and the CBS series Harts of the West in 1993—one of Lloyd’s final appearances before his death in 1998. “Unlike a lot of Hollywood actors, my dad really loved acting and wanted to turn his kids on to it,” Bridges told Entertainment Weekly. “As a kid, you don’t want to do what your parents want you to do. You want to be like all of the other kids. So I had a lot of resistance to acting being my path.” Photofest Before she became a star in her own right, a 17-year-old Liza Minnelli took the stage with her movie star mother, Judy Garland. In the 1964 show Judy Garland: Live at the London Palladium the pair sang, danced, and bantered together, sometimes awkwardly (“You’re my favorite guest star,” Judy told Liza, who replied, “Well, you’re my favorite mother.”) Not long after the mother-daughter duo took the stage, Liza came into her own as a stage performer, starring in Cabaret —which won her an Oscar—and several one-woman shows. Courtesy Everett Collection Some actors wait years for their big break, but Tatum O’Neal had hers at the unripe age of 10. Tatum starred alongside her father Ryan O’Neal in the 1973 film Paper Moon, which eventually made Tatum the youngest actor to ever win an Academy Award. But apparently their father-daughter rapport wasn’t as good off-camera—in her 2004 memoir A Paper Life, Tatum wrote that the collaboration “sort of destroyed us,” and alleged that Ryan, jealous of his scene-stealing daughter, had punched her when he learned of her Oscar nomination. Ryan flatly denied his daughters allegations, saying, “It is a sad day when malicious lies are told in order to become a ' bestseller.’” Courtesy Everett Collection Dale Earnhardt was born into a racing dynasty. And even though he never got to race with his father, Ralph, he lined up with his son, Dale Jr., on the track from 1999 to 2001. NASCAR, Junior said, at 15, is in his blood. “I wanna be a racecar driver someday. It’s a great sport. I love it to death, you know. It’s all I’ve ever known, racing,” he told CBS. Dale, in his signature black No. 3 Chevrolet, was already well-established as one of the most successful drivers in NASCAR history with nearly 70 victories over his 20 year career. But tragedy struck the family at the 2001 Daytona 500. Dale Sr. was killed when he crashed into the wall on the final lap of the race, while his son was also on the track. Dale Jr. has never lived up to the lofty standards set by his father, though he has turned into one of the sport’s most marketable characters. AP Photo When Sylvester Stallone needed someone to play Rocky’s 14-year-old son, Rocky Jr., in the series’ fifth chapter in 1990, he didn’t have to look very far. His own son Sage Stallone was the right age and, as an added bonus that few other actors could offer, actually looked like his father. It was Sage’s first appearance in a movie career that put him in 10 more forgettable films. Rocky V ends with the father and son running up the iconic steps of the Philadelphia Art Museum and Rocky, Jr. taking his father inside for the first time. “Well you're never to old to learn somethin' new,” he says to his father, “You’re gonna love Picasso.” Rocky answers: “Yeah, well I love almost everybody.” United Artists / Courtesy Everett Collection There are many ballplayers who followed their fathers’ cleats into the big leagues—baseball is, after all, the game of fathers and sons. But only two father-son duos have ever played in the majors at the same time, Ken Griffey and Ken Griffey, Jr. and Tim and Tim Raines Jr. In 1989, 19-year-old Ken Griffey, Jr. came up with the Seattle Mariners while his father was playing for the Cincinnati Reds at the tail end of a standout career. A year later, the Griffeys took it one step further and played on the same team when Senior signed with the Mariners. As teammates, the Griffeys made history one more time when they blasted back-to-back home runs against the California Angels. “My dad said to go play and have fun,” the younger Griffey told Sports Illustrated. “And that’s just the way it is.” Bill Chan / AP Photo Sofia Coppola made her acting debut before she even knew she was acting. Cast as Michael Corleone’s baby boy in the brilliant baptism/murder scene at the end of Francis Ford Coppola’s Godfather, Sofia was essentially a living prop. Her father didn’t give her much of a promotion for the second film in the series when she was just another child on the ship that brought Vito Corleone to the United States. In The Godfather Part III, however, she had a starring role, as Mary Corleone, Michael’s youngest daughter. Though she is sheltered from the family’s questionable business doings, she is forced to confront them when she falls in love with her cousin Vinnie Mancini-Corleone, who is Michael’s choice to take over. Spoiler alert—it does not end well for her. In real life, however, Sofia’s trajectory was far more successful, going into her father’s business, too, and has directed five features including The Virgin Suicides and Lost in Translation, for which she won a Best Screenplay Academy Award.
