Jennifer Lawrence and Liam Hemsworth smiled for the cameras on their way into a screening of The Hunger Games hosted by the Cinema Society and Calvin Klein in NYC this evening. Jennifer changed into a sexy green dress for the event after donning two different looks at The Late Show studios earlier in the day. Jennifer's had many hot moments during her nonstop press tour for the film, which hits theaters on Friday. Last week she traveled to LA, Berlin, Paris, and London for premieres with her costars Josh Hutcherson and Liam. The boys headed to Toronto yesterday, before they met back up with their leading lady in the Big Apple.

Katie Holmes and Suri stopped by a toy store in NYC this afternoon. Suri got adventurous as she lept over a puddle on her way into the shop, while Katie held onto both her daughter's hand and a fuzzy pink blanket. Suri wasn't around earlier in the day when Katie was spotted out enjoying the warmer Spring weather with her mom Kathleen Holmes, who also made an appearance in the Big Apple yesterday. Kathleen, Katie, and Suri visited a Whole Foods, where they were seen holding hands as they crossed the street.

Jennifer Lawrence debuted two new looks for her appearance on The Late Show in NYC today. She arrived wearing a short black cutout dress by Raoul with Jimmy Choos and was later seen leaving the studio in a long-sleeve Prabal Gurung look and the same sexy heels. It's been a busy month of press for Jennifer as she gears up for this Friday's release of The Hunger Games. Her costars Liam Hemsworth and Josh Hutcherson have also been promoting the film, and the duo popped up in Toronto for a premiere yesterday. Liam was in the Big Apple this morning for a visit to GMA where he talked about prepping for the movie by cutting back on calories and shared his experience working with Jennifer. Jennifer will continue making the rounds this week with a stop by Late Night With Jimmy Fallon and an interview with Chelsea Handler.

Sienna Miller hit the streets of London to film a commercial for Amore Pacific skin care line today. She covered her baby bump in a striped top for the cameras, and ducked into a van for touch-ups in between takes. Sienna's expecting her first child with her rumored fiancé Tom Sturridge and the couple were spotted showing PDA in NYC earlier this month. They've kept pretty quiet on their upcoming addition, but Sienna did share her excitement about the baby in an article for Vogue UK's April issue. There's another project on the horizon for the duo, since Tom has On the Road coming out later this year. The first On the Road trailer was released this month, and features Tom as well as his costars Kristen Stewart and Garrett Hedlund.
