Photographers caught up with Nick Lachey and Vanessa Minnillo out and about in LA last night. It's been a while since we've seen these two together while Vanessa's been enjoying spring break fun and Nick gears up for his new Fame-inspired show on MTV. Unfortunately, it sounds like all may not be all sunshine and rainbows — Vanessa apparently stopped by Baron Davis' surprise birthday party over the weekend where she acted cold to fans and avoided cameras. Definitely a little odd considering how much she seems to love a photo op.
