Christina Applegate is rocking quite an engagement ring.
On Saturday night, the newly engaged actress, 38, briefly flashed her bling while strolling through Los Angeles International Airport.
No word on a wedding date -- but she is likely keeping that under wraps.
Her pal Alyssa Milano tells UsMagazine.com Applegate kept her engagement to Porno for Pyros rocker Martyn LeNoble "a secret from everyone." She said she is "thrilled" for Applegate, her costar in the upcoming comedy Hall Pass. "They are an amazing couple," she told Us, "and I think they are great."
