Kate Beckinsale

Tom Cruise supported his fellow action stars when he dropped by the Star Trek Into Darkness premiere in LA yesterday. He met up with director J.J. Abrams at the afterparty at AV nightclub and chatted with Paramount Pictures CEO Brad Grey. Meanwhile, the film's star Zoe Saldana created a buzz of her own when she walked the gray carpet in a sheer Rodarte dress. She later met up with an Alberta Ferretti-clad Kate Beckinsale inside the event, as well as her costars Chris Pine and Zachary Quinto. Jennifer Morrison created a red carpet moment when she dropped by the premiere while wearing an Edition by Georges Chakra powder blue jumpsuit. Also in attendance was Zoe's costar Alice Eve, who previously told us that she had trouble keeping all the secrets about the Star Trek script to herself.

Kate Beckinsale was decked out in a pink Alberta Ferretti dress that showed off her sky-high heels at the Met Gala in NYC this evening. The gown had a high hem in the front, while it was long in the back, which meant it also put her perfectly toned stems on display. Kate was without her usual date, husband Len Wiseman, but she had plenty of fellow fashionable stars to rub elbows with all night long.

Jennifer Aniston and Courteney Cox were together last night in LA to celebrate Mandy Ingber's new book, Yogalosophy: 28 Days to the Ultimate Mind-Body Makeover. Also out for the bash at Soho House were Ricki Lake and a Monique Lhuillier-clad Kate Beckinsale. In addition to Jen and Courteney's long-term friendship, Jennifer and Mandy also go way back — they've been practicing yoga together for years, and many credit Mandy with keeping Jennifer in such amazing shape.

Two weeks ago, Jennifer wore another short black outfit to celebrate one of her own debuts. Jennifer Aniston wore Dior to the premiere of her latest project for Lifetime called Call Me Crazy: A Five Film. To promote Call Me Crazy, Jennifer visited The Ellen DeGeneres Show as well, and there she shot down any rumors that she and Courteney will reunite professionally for a Friends reunion.

During her chat with Ellen, Jennifer also spoke about her fun-loving fiancé Justin and his love of scaring her by hiding behind drapes, or practicing what he calls "trickery." They're, of course, working on the joint project of organizing a wedding. The latest on their big day comes from Us Weekly, which reports today that Jen and Justin are delaying their wedding until later in the year for a variety of reasons.

Kate Beckinsale was back in a bikini in Mexico yesterday, after popping up poolside on Wednesday and Thursday as well. She chatted with friends in a black two-piece and ordered lunch from the staff. Kate's daughter Lily is also along for the getaway and lounged in the sun with her mom earlier this week. Kate's just one of many celebrities enjoying Spring vacations, and she's not the only star to travel to Mexico. Molly Sims and her family headed south for the holiday weekend, while Reese Witherspoon recently wrapped up her own Mexican escape with husband Jim Toth.

Kate Beckinsale wore a bikini while relaxing in Mexico yesterday, after also hanging poolside in a white bikini top on Wednesday. She's just one of many celebrities vacationing during Spring break, including Heidi Klum and her family, who are currently in Hawaii.

Kate showed off her fit physique under the sun after participating in a mock yoga class during a skit on After Lately this week. Kate joked that Chelsea Handler's body isn't looking "great" and critiqued her "toxic lifestyle" for the clip, which was all in good fun. Kate will be back on screen later this year, when her next movie, The Trials of Cate McCall, is released.
