Jennifer Garner was on mom duty with daughters Seraphina and Violet in LA on Saturday morning. She took the girls to ballet class while Ben was taking care of his own errands nearby in the city. The two parents have been sticking close to home with their new son Samuel over the past few months, though they did make time for date night this week. Ben showed off his hot new haircut out with Jennifer on Wednesday afternoon before their romantic dinner together. Ben has been putting the finishing touches on his latest directorial and acting project, Argo, while Jen is getting ready for a Summer of promoting her film The Odd Life of Timothy Green. While we await their next projects, we also took a look back at some of Ben's older work in our fun mashup video of hot guys proposing in some of our favorite movies and TV shows.

Reese Witherspoon held onto her latest stylish bag and covered up her baby bump as she made her way through LAX on Friday. The actress was headed out of town after another busy week at home taking care of errands and spending time with her family. Pregnant Reese took her dogs for a hike in Brentwood and scoped out a construction site, which prompted rumors that she and husband Jim Toth are working on a new home as they prepare for their upcoming arrival. Reese is on a break between movie projects, but she's still keeping up her red-carpet appearances. Reese attended the White House Correspondents' Dinner in Washington DC just last Saturday. With a little one on the way, Reese is having an amazing year already, which is earning her high placement in the PopSugar 100.

Kristen Stewart rocked flats for her interview on The Tonight Show With Jay Leno that aired on Friday evening. She assured Jay and the audience her choice of footwear wasn't because she wanted to get out of wearing heel. Kristen apparently suffered yet another injury while filming her Breaking Dawn Part 2 reshoots in Vancouver this week. The "puncture wound" came while capturing even more of Bella's first hunt as a vampire, which Kristen says will be awesome when the movie hits theaters in November. Now she's switching gears to promoting Snow White and the Huntsman and she'll be heading to London next week for the junket — where she'll meet our lucky I'm a Huge Fan winner! — and premiere. First up, however, she's rumored to be making a stop off at the Met Gala in NYC on Monday.

Stars and their kids had fun this week! Gwyneth Paltrow was out and about with Moses and Apple in London, and Brad Pitt spent quality time with his son Knox during a visit to Legoland not far away. George Clooney ventured to Houston ahead of his 51st birthday tomorrow, as Kristen Stewart made an appearance on Jimmy Kimmel Live. That's not all that went down — check out what the other stars were up to.
