Liam Neeson was the man in the middle of a January Jones and Diane Kruger sandwich last night at the LA premiere of Unknown. January's latest edgy look was an Alexander McQueen creation, while Diane chose Dolce & Gabbana. Diane had Joshua Jackson by her side after she took a quick trip to NYC this week to chat up her movie on Regis and Kelly. Josh welcomed her home with flowers, and they were one of the many adorable couples spending the holiday together. Diane told us that it was the first time in three years they've been together on Feb. 14 and that Josh pulled out all the stops for a sweet celebration. January, meanwhile, shared all about shooting in Berlin with Diane and Liam, saying that they were able to spend lots of time together on set and off. Liam had nothing but good things to say about working with the ladies, adding that he particularly loved the script because it was a thriller with a brain. A Stella McCartney-clad Kim Kardashian even made an appearance on the black carpet, and she stopped to chat with us about how she's rooting for a Natalie Portman win at the Oscars and how her young pal Justin Bieber proved that he was a class act by gracefully handling his best new act loss at the Grammys on Sunday — make sure to check out PopSugar Rush later today for more from Kim at Diane and January's big evening!
