Seth McFarlane threw a star-studded holiday party at his private estate in Beverly Hills on Saturday, Dec. 12, with such celeb guests as Christina Aguilera, Katharine McPhee, Marilyn Manson, John Stamos, Scott Speedman, Ben Savage, Adam Carolla, Kimberly Stewart, Liz Gilles, LA Reid, Cheryl Burke, Courtney Love, Bill Mahr, Meghan Trainor, and Darren Criss.
A source tells Us Weekly that the soiree was “really classy and decorative” and that the female guests wore fancy sparkly dresses, while the men donned suits and ties. The party featured multiple rooms with different whiskey bars, a giant inflatable snow globe outside, carolers, and even a s’mores bar at the back patio.
‘90s stalwarts Manson, 46, and Love, 51, were seen chatting closely at one point, while after Love buzzed about around the party.
McFarlane, 42, paid special tribute to Frank Sinatra’s 100th birthday as he addressed his guests— with the late legendary singer’s youngest daughter in attendance.
“Tina Sinatra’s sitting right in front of me,” McFarlane told his guests. “I’m going to try not to f–k this up,” he joked before singing a set of some of Sinatra’s most famous songs, dueting with both Gilles and McPhee.
“He sounded incredible singing Sinatra songs, like right on point!” the source tells Us. “And McPhee killed it. Her voice is crazy,” the source adds, noting that the pair also sang a duet of “Baby It’s Cold Outside,” and “had really great chemistry.” Later in the evening, Trainor took the stage to perform.
Glee alums Stamos and Criss also hung out together during the party, chatting throughout the night.
Meanwhile, Aguilera and her fiancee, Matt Rutler, were seen cozying up together on the couch.
“She looked great,” says the source.
