Shake that healthy butt!
After Jennifer Aniston and Justin Theroux tied the knot in an intimate backyard wedding in Los Angeles last Wednesday, the newlyweds celebrated alongside guests into the early hours of the morning – with quite the eclectic playlist.
"The party went until 3 a.m.," an attendee tells PEOPLE in this week's cover story, "and everyone was dancing. Courteney [Cox] was the last one to leave!"
Music from the couple's playlist included "Real Love" by Mary J Blige, "Billie Jean" by Michael Jackson, "It Takes Two" by Rob Base and DJ E-Z Rock, and "Only Girl (in the World)" and "B---- Better Have My Money" by Rihanna.
Deejay Samantha Ronson, who was in attendance for the festivities, also spun "Baby Got Back" by Sir Mix-A-Lot.
Shortly before midnight, guests were even treated to their own private concert from Australian singer Sia, who performed her hit "Chandelier."
And although the evening didn't turn out to be a birthday party for Theroux, as guests were initially told, they still sang "Happy Birthday" to the groom, who turned 44 on Aug. 10.
