Apparently birthdays and breakdancing go hand-in-hand for Justin Theroux.
After granting fiancée Jennifer Aniston her wish by spinning on the floor when she turned 43, he recently showed off his skills at a joint birthday bash for pals Ellen DeGeneres and Portia de Rossi. But this time, Julianne Hough, 24, gave the actor, 41, a run for his money.
“[They] decided to have a breakdancing break-off,” DeGeneres said Thursday on Ellen. “So we wanted to roll the rug back so they could spin on the floor. And [Julianne] was wearing a skirt and goes, ‘I need pants.’ … She and Justin Theroux had a huge dance-off. It was crazy. It was a really fun night. She’s an amazing dancer.”
Ryan Seacrest, who happened to be DeGeneres’s show guest for the day, also had praise for girlfriend Hough, whom he said is “amazing at literally everything.”
But there are times when he is slightly threatened by his girlfriend.
“She’s such an athlete,” he explained. “Literally, I’m afraid to do stuff with her sometimes because I’m afraid I’m going to get injured.”
