Madonna has been making the Oscar party rounds, but one thing's been missing: her younger man Jesus Luz! 

On Thursday, she was spotted getting super friendly with Zachary Quinto during Grey Goose's party at Soho House. "They were very fast friends and very interested in what one another had to say," an eyewitness tells me.

And just last night, she hit Moet & Chandon's fête for photographer Tom Munro's latest book with a new younger man by her side.

Whoever the new guy is, he certainly seemed to be putting Madge in a good mood...

"She was dancing playfully in the VIP area," a source tells me. "She was sitting very close to her mystery man."

The Material Cougar only stayed for about 10 minutes, but Hollywood Life has some video of her quickie appearance.

Also rolling solo at the same soiree was Justin Timberlake. The singer came around 8 p.m., sans Jessica Biel. Unlike Madge, JT stayed for more than an hour, sipping champagne and chatting with the photographer.

He also opted out of going into the VIP section and refused the umbrella coverage offered for partygoers getting their cars in the rain.

Maybe he's more down to earth than we thought?
