While Brad Pitt was off in France sneakily marrying Angelina Jolie, his ex-wife Jennifer Aniston has been, well, everywhere — especially in the headlines. The 45-year-old attended the Los Angeles premiere of her film Life of Crime on Wednesday night, walking the red carpet with a big smile just hours before the Brangelina wedding news hijacked the internet. While her sparkly silver Saint Laurent showed off one of her best assets — those legs! — the ill-fitting frock accentuated her midsection, sparking new rumors that she and fiancé Justin Theroux, 43, are expecting their first child. The bulky black blazer she had over the dress did nothing to help the silhouette. [Related: Brad Pitt Steps Out Wearing Wedding Ring] However, Aniston has already shot down pregnancy rumors. In a new interview with Extra, the actress tackled the typical rumors she's been facing for years, ticking down a list, saying, "I'm not pregnant. I'm not married. What else?" Another tabloid tale, courtesy of In Touch on Wednesday, was that Aniston recently suffered a miscarriage. However, she let her rep handle that one, telling Gossip Cop the story was "completely fabricated." The actress's Wednesday night appearance on Jimmy Kimmel Live was much more light-hearted than miscarriage talk, but it did include chatter about babies. The fabulously coiffed star rocked a strapless LBD for her chat with her good pal Kimmel. During the silly segment, Aniston talked about visiting Kimmel's home after the recent birth of his new daughter, Jane, and revealed that she — gulp — sampled his wife Molly McNearney's breast milk. We'll let her give you the details: Kimmel then orchestrated a mini Friends reunion on a replica set that he had created of Rachel and Monica's kitchen with Courteney Cox and Lisa Kudrow making cameos. The night before, the busy actress was out again — this time with Theroux — feting another close pal and late night host, Chelsea Handler. The couple attended the Chelsea Lately finale party at Craig's in L.A. with a source telling Us Weekly that The Leftovers actor "had his arm around [Aniston's] shoulders. They were having such a fun time." Aniston and a star-studded group including Sandra Bullock and Gwen Stefani had appeared on the finale, which aired that night. While Aniston has been out and about non-stop this week, there was actually one place people thought she would go that she didn't. On Monday, Theroux went stag to HBO's Emmys bash, where he chatted with Girls star Allison Williams and Emmy winner Julianna Margulies. He even danced a bit — no surprise as he has some pretty fancy dance moves. Many were surprised that Aniston didn't accompany him to the party. Aniston may want to take a few days off from the public eye now that news broke that her ex-husband Pitt, whom she was married to from 2000 to 2005, married Jolie in France on Saturday. For most of the last decade, the trio has been tabloid fodder because Pitt fell in love with Jolie on the set of Mr. and Mrs. Smith while still married to Aniston. No doubt she'll be plagued with questions about the union — whether Pitt tipped her off that it was happening, if she'll be sending them a gift, and other equally awkward inquires. However, Pitt's relationship with Jolie seems like old news to the actress, who has a wedding of her own to plan. During her interview with Extra, she refused to divulge details about a possible date ("I don't know," she said, before quipping, "Really, you think I'm going to tell you here?"), but she talked about the institution of marriage. "I just think you live in the moment," she said when asked how she knew Theroux was the one. "I think you learn as you get older, too. Marriage is a wonderful thing. A relationship is a wonderful thing. It's a way to discover who you are." Perhaps she'll soon be following in Pitt's footsteps… back down the aisle.
