Jessica Alba Ashton Kutcher

Well, in the movie Valentine's Day, anyway!

Yesterday Ashton Kutcher was spotted getting cozy with his co-star Jessica Alba in Hollywood, and the onscreen lovebirds were giggling, tickling each other with flowers and engaging in all sorts of flirty behavior! But what would Jennifer Garner say about this!? We caught Ashton smooching her just the other day, so it looks like these characters have a little love triangle going on!

Sooo...which starlet would you pick? No offense to Jen, but we're totally on Team Alba on this one!
