Vanessa Minnillo's Death Grip

Vanessa Minnillo puts the squeeze on her main man, boyfriend Nick Lachey, before catching an American Airlines flight out of LAX airport on Monday morning.

Just last week, the so-far-scandal-free couple shopped for first-birthday presents for the Nick‘s niece – and brother Drew‘s daughter – Isabella (whose b-day was on March 23) at children’s boutique Petit Tresor in Beverly Hills. They scooped up a pink robe, a tea set, pink-and-gold sneakers and a ballerina-themed puzzle for the baby’s party.

Nick, 33, and Vanessa, 26, have been dating for over a year now. 15+ pictures inside…

Who will walk down the aisle first? Nick & Vanessa or John & Jessica?
