It's getting serious, guys!

On Tuesday Jennifer Lawrence landed at Los Angeles International Airport, and while she covered her pretty face with her sweater, we got a full view of the Love Button Movement pin on her bag. As you know, J. Law's boyfriend Chris Martin has a handful of these pins (and he literally wears them every day), so we have a feeling he gifted her with this one! First comes love, then comes marriage...

But really, the Love Button Movement is a nonprofit organization which is a "good old fashioned, boots-on-the-ground, grassroots effort to bring people together in loving ways throughout the real world."

The 24-year-old actress attended the premiere of Serena on Monday at the BFI London Film Festival, but she left for the U.K. last Friday, so it looks like she had plenty of down time with her man. Chris is reportedly working on new music in London, so hopefully he'll come back to the states to hang with his sweetheart before she kicks of a crazy promotional tour for The Hunger Games: Mockingjay - Part 1 next month.

And just how serious are these two lovebirds? Apparently the 37-year-old singer recently met Jen's mom and she wants him to come celebrate the holidays with the family! Jennifer's grandmother, Carolyn Kloch, reportedly told The Sun, "Jennifer's mum flew to Los Angeles to meet Chris. We will have to get another chair for the dinner table at Christmas! The family is getting so big we might have to split up for gatherings."
