At Paris Fashion Week, which kicked off Tuesday, even the pastries are over-the-top. " Heidi Klum surprising @Roberto_Cavalli with a birthday cake at his 40th anniversary party and 70th bday!!" fashion blog Modelinia tweeted on Wednesday. Klum just celebrated a milestone of her own, leaving Victoria's Secret after 13 years. Supermodel Hilary Rhoda was happy to celebrate at Roberto Cavalli's 40th anniversary soiree on Wednesday during Paris Fashion Week. "Wearing one of his sexy dresses!" Rhoda tweeted before the event and added a little shine with the help of another designer. "Thanks, Chopard ;)" she tweeted again. InStyle editor Ariel Foxman and country darling Taylor Swift made a fine-looking pair during Paris Fashion Week at Roberto Cavalli's 40th anniversary celebration as well. "Taking in the Cavalli gala w @taylorswift13," Foxman tweeted. Swift, 20, made sure to mingle, also making friends with actress Rachel Bilson. The singer sweetheart enjoyed her time in the French capital, tweeting to her fans on Thursday, "Leaving France, eating crepes. Lovely times. I <3 Paris." Brazilian supermodel Izabel Goulart stole some time away from the runway at the beginning of Paris Fashion Week to indulge in some high-end spending. "Goulart at Goyard! Shopping time!" she tweeted. Model Chanel Iman spent time with her "favorite twins" at the amfAR AIDS Research Gala during Milan Fashion Week, snapping an affectionate shot with Dean and Dan Caten, the identical twin brothers behind designer label DSquared. "I freakin LOVE THEM !!" she tweeted. Iman loved Gucci even more, though, draping herself "head to toe" in the Italian label for the event. "Italy watch out Miss Americas coming through lol;)" she added. "At the D&G event with @annadellorusso," Victoria's Secret angel Alessandra Ambrosio tweeted from a Milan fete celebrating Naomi Campbell's 25-year career with Dolce & Gabbana. Dressed in a sleek black D&G frock, Ambrosio sidled up next to the more fashionably adventurous Nippon Vogue editor Anna Dello Russo. First, Love Magazine snapped fashion photographer Manuela Pavesia "looking very ‘Marc Jacobs'" after a Prada show during Milan Fashion Week. Her outfit resembled the designer's signature black pleated kilt and collared shirt look. But it wasn't long before the roles were reversed: "And Mr Marc Jacobs dressed as Manuela Pavesi," the magazine tweeted two days later. So who wore it best? Pop star Kylie Minogue was apparently very impressed with Dolce & Gabbana's presentation at Milan Fashion Week. And she was lucky enough to meet the design duo backstage, posing with Stefano Gabbana and Domenico Dolce. "Fresh, white, lace and leopard…and bling…mmmMMMM!!!" Minogue tweeted. "Burberry front row," The New York Times' fashion critic tweeted from London Fashion Week sharing a peek at the ultra-chic guest list visible from her exclusive perch. From right: tennis phenom Serena Williams, Sarah Jessica Parker, British actor Douglas Booth, model Alexa Chung, Breaking Bad star Aaron Paul, and English TV personality Donna Air. Fashion dream team Anna Wintour and Kanye West crossed paths at Wintour's second annual Fashion's Night Out in New York earlier this month. Although Fashion Week has moved across the pond now, the Marc Jacobs team posted some new photos this week. "And of course Anna and Kanye made it out," Jacobs tweeted.
