Chris Martin Late Night with Kylie Minogue ... Hunger Games Over?

0624-main-chris-martin-kylie-minogue-inf-01Chris Martin was arm-in-arm with Kylie Minogue -- at 1:30 AM in a London park -- which may or may not be news to his GF of several months.

Chris and Kylie were strolling together early Monday morning after her concert in Hyde Park -- and the late/early hour of has some people thinking he and Jennifer Lawrence are dunzo.

J-Mart seemed pretty tight earlier this month snuggled up in the back of Bono’s SUV, and it's entirely possible Chris and Kylie were just a couple of non-banging pals getting fresh air.

Y'know what they say, though -- the nighttime is the right time. For what? We'll leave that up to Jennifer.
