The Runaways star Kristen Stewart arrived in NYC Monday night.

Robert Pattinson was on set in London for Bel Ami on Monday.

Kate Winslet relaxed with a cigarette and a drink while wearing a small black bikini on the deck of a boat in Puerto Vallarta, Mexico, today. The Oscar-winning actress made shocking headlines today when her lawyer announced her split from her husband of seven years, Sam Mendes. She kicked off her vacation with her two kids over the weekend when she headed out on the boat in her black two-piece top — all of which is lined up with the separation announcement, although it apparently happened months ago.

Jeremy Renner went out to dinner at Koi in LA over the weekend.

Kellan Lutz was in a tight white shirt Friday as he ran errands and got his car washed in LA. Ashley Greene, meanwhile, wore a cute purple outfit for a meeting across town at a Starbucks, where she was deep in thought as she read a script. The Twilight pair reunited in the evening, when Kellan joined Ashley for drinks at STK after he ate at Agura with friends. They could have been getting a head start on his birthday celebration, since he turns 25 today! Both Kellan and Ashley have been jetting around the world promoting other projects before Eclipse hits theaters in June — check out the first trailer.
