Tom and Suri Cruise left their Manhattan hotel today to run some afternoon errands. Suri seemed reluctant to cover up her colorful dress, but Tom brought along her red Dolce & Gabbana jacket just in case. The 6-year-old spent the last few days exploring the Big Apple with Katie, including a stop at FAO Schwarz, before Tom returned home yesterday. He racked up an impressive amount of frequent flier miles over the past few weeks traveling around the world promoting his latest blockbuster, Mission: Impossible — Ghost Protocol. Tom made it back to the East Coast in time for Monday's stateside premiere of the film and, more importantly, Katie's 33rd birthday! Katie turns 33 on Sunday, but we'll have to wait and see if, like last year, she celebrates by seeing a Broadway production.

Jennifer Garner and Seraphina stayed warm in sweaters on a stroll around LA this morning.

Jennifer said in InStyle's January 2012 issue that she doesn't count herself among celebrities who can wear skinny jeans during their pregnancies.

The Garner-Afflecks have been busy getting ready for the holidays, after Jennifer and Ben Affleck went Christmas shopping over the weekend. Ben has also been hard at work on his upcoming directorial project, Argo, but he's taking any time that he can for his growing family.

Jennifer Lopez arrived for the third day of American Idol Hollywood Week auditions in Pasadena yesterday. She waved to fans and entered the arena solo, and later in the day she got a visit from her boyfriend, Casper Smart. Casper made a low-key entrance though a back door. It wasn't apparent, though, if he arrived in the Bentley Jennifer allegedly gave him as a gift!

J Lo and Casper's relationship seems to be going strong following their romantic Thanksgiving trip to Hawaii. One person, though, might not be thrilled. Her ex-husband Marc Anthony is reportedly unhappy about Casper and is very "stressed" over the situation. Jen's surprising split from Marc grabbed major headlines back in July, and it ranks among the most shocking celebrity breakups of 2011.
