In December she was briefly linked to Kings of Leon bassist Jared Followill, and the Dancing with the Stars pro now seems to be spending some quality time with funnyman Dane Cook.
Hough, 21, attended Cook's surprise performance at Hollywood's Laugh Factory Saturday night. A source says that after his set, the comedian walked over to Hough, who was seated at a private table, and "kissed her, and they quickly left together."
The duo's night continued as they headed for dinner at Sam Nazarian's Katsuya Hollywood, where they ate in the very private Dragon Room.
"They looked very happy together, and very affectionate," says an onlooker. The two sat side by side and shared a few of the restaurant's specialty dishes before heading out of the restaurant together.
The two were also spotted chatting at the CAA Golden Globes party at the Buffalo Club earlier this year.
Reps for both Hough and Dane had no comment.
