She can't spend every waking minute with him, you know!

On Wednesday evening Selena Gomez and new bestie Cara Delevingne went to a private charity party in St. Tropez, and while SG looked goooorgeous, her new flame Tommy Chiabra was nowhere to be seen. But given how much time they've been spending together, we have a feeling they hooked up later in the evening...

Selena and on-again/off-again boyfriend Justin Bieber ended things less than a month ago, and though he's been spotted with several flings since then, yesterday he told X17 photographers that Selena is "beautiful" when asked what was going on with them. Hmm...think a Jelena reunion is imminent when the starlet returns from her Eurotrip? We'll put a hundred bucks on it...
