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 after party 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 grey carpet in a sheer Rodarte dress. She later met up with an Alberta Ferretti-clad Kate Beckinsale inside the event, as well as her co-stars 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 co-star Alice Eve, who previously told us that she had trouble keeping all the secrets about the Star Trek script to herself.

It's no secret that Jennifer Aniston is a devoted yogi. She's been practising three to four days a week since 2005, with her close friend and wellness advisor, Mandy Ingber. Last night Jennifer, along with Courteney Cox and Kate Beckinsale, turned out to celebrate Mandy's new book, Yogalosophy: 28 Days to the Ultimate Mind-Body Makeover (approx $18). The book is a unique plan created to help readers achieve healthier bodies and happier minds. There's an eating plan, along with exercises to tone and strengthen the body, and enlightened tips to help shift the mindset to a positive one. Click through to see pictures from the event.

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 rumours that she and Courteney will reunite professionally for a Friendsreunion.

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 organising 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 mum earlier this week. Kate's just one of many celebrities enjoying a holiday during the US Springtime 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.

Goodness, this has been an exciting week for film! Shailene Woodley nabbed a lead role, Kristen Wiig and Will Ferrell are collaborating, Christina Applegate is in talks for a reboot, Tom Cruise may play a famous TV man, and Ryan Gosling has added Saoirse Ronan to his directorial debut. See all those and more in this week's biggest casting news!

There have been plenty of stars out at London Fashion Week but the Burberry show is always one that attracts some of the biggest names — and in numbers. Yesterday’s show brought together an eclectic group of US and UK style setters, including Rosie Huntington-Whiteley — a stand-out in a red blazer and pants ensemble — Olivia Palermo, Kate Beckinsale, Freida Pinto, Downton Abbey’s Michelle Dockery, and Rita Ora, who wore her support in the form of a T-shirt for best friend Cara Delevingne, a runway favourite. It wasn’t just about the ladies, though. Burberry model George Craig modelled a metallic trench while UK rapper Tinie Tempah wore a printed shirt.

Even with New York Fashion Week's star-studded styles fresh on our minds, the London shows supplied us with another round of famous faces (and killer outfits) taking their seats in the British capital. At Burberry Prorsum, we spotted Rosie Huntington-Whiteley working a bold red suit, Kate Beckinsale looking fresh as ever in all white, and Freida Pinto exuding easy glamour in her Burberry peplum top and cropped trousers. What's more, Olivia Palermo stepped out in yet another fashionable front-row ensemble at Antonio Berardi. With London Fashion Week wrapping up tomorrow, join us as we take a front-row look at the best celebrity looks before we head on to Milan. — Additional reporting by Melody Nazarian
