Sad Patrick Schwarzenegger and Happy Miley Cyrus Lead This Weekend’s Hottest Star Sightings

Patrick Schwarzenegger is back in Malibu following his flirtatious, party-hardy Spring Break in Cabo (because duh, he’s a hot college boy), but he was spotted looking super glum as he went out to lunch with friends.

Meanwhile, girlfriend Miley Cyrus was spotted in Las Vegas looking chipper as usual.

Is there trouble in paradise for Hollywood’s young lovebirds?

If she was bummed out, it didn’t show. Cyrus partied at Vegas hotspot, Omnia Nightclub at Caesar’s Palace, with gal pal Stella Maxwell, who she was with at SXSW earlier this week.

She posted these party pics from Vegas to her Instagram, no mention of Schwarzenegger whatsoever:

People notes Cyrus was “very mellow” at her VIP tables, where she sipped on vodka and tequila, danced with friends, and did “nothing that is thought to be ‘typical Miley'”, however GossipCop notes that her behavior didn’t actually give any indication that she was bummed out.

If anything, judging by her Instagram, she looked pretty happy and like she was enjoying herself.

Was Schwarzenegger supposed to accompany Cyrus to Vegas? Will they be reuniting soon, or not?
