Jonathan Rhys Meyers is Hot and Sweaty

Johnathan Rhys-Meyers is dripping sweat as he walks out of a Los Angeles gym wearing brown velour pants and toting around a blinding yellow Puma workout bag.

He reportedly goes to Crunch gym is West Hollywood and curls a 50-lb. barbell.

The 29-year-old Irish hunk spent the day pumping iron and apparently lost a couple inches on his waist — his pants are majorly falling down!

Jonathan Rhys-Meyers‘ new Henry VIII soap opera mini-series The Tudors starts airing tonight @ 10PM ET/PT on Showtime.

UPDATE :: The latest “Cushion Pushin’” from Page Six:

NOTE to Jonathan Rhys Meyers: Next time, get a hotel room! The Irish-born hunk, who stars as Henry VIII in the new Showtime series “The Tudors,” sashayed into The Plumm with his pony-tailed brunette love Reena Hammer under his arm the other night. They immediately retired to a couch and launched into a frenzied make-out session as a crowd of revelers became voyeurs. “It was really a scene. She straddled him, and they were at it for some time,” our spy said. When the steamed-up duo finally called it quits, they left without even bothering to have a drink.
