Jennifer Lawrence and Chris Martin Show Off Their 'Love'

Subtle, guys! Jennifer Lawrence touched down at LAX on Tuesday sporting a "love" pin on her purse. Simple enough, but if you're a Coldplay fan, the button should look familiar. Chris Martin has been photographed wearing the very same one on numerous occasions.

While it seems likely that the 37-year-old rocker gave his girlfriend one of his spare accessories, the pin is actually from the Love Button Movement. According to the website, the movement is "a good old fashioned, boots-on-the-ground, grassroots effort to bring people together in loving ways throughout the real world."

Chris has been supporting the cause for months, even before he began dating the 24-year-old actress. In February, the Coldplay frontman wore the pin during one of his last date nights with Gwyneth Paltrow, right before they decided to consciously uncouple.

As for J.Law and Martin, things appear to be heating up. The pair has become less shy with their relationship as the Hunger Games star has stepped out to support Chris at many of his concerts.

"It seems they are definitely getting more serious," a source told People last month. "Whenever Chris is not spending time with Apple and Moses at his Malibu, [California], house, Jen is there. Chris and Jen always time it so that after Gwyneth picks up the kids (Apple 10, and Moses, 8), Jen will arrive in Malibu minutes after."

Although it's unclear if Lawrence and Paltrow have spent time together yet, the 42-year-old Iron Man actress has reportedly given her seal of approval.

"Gwyneth is very happy for Chris, that he has moved on and found someone else," a source told E!, who first broke the relationship news. "Their split has been remarkably amicable and they both just want the best for one another."

Guess there is nothing but "love" to go around.
