If any of you tuned in to 'X Factor' last season, you probably noticed that Demi Lovato's eyebrows grew awfully fast awfully quickly. Now, she's telling us how!

In a recent Q+A, the interviewer asked Lovato how she got her brows so full and lush so fast, and her response was pretty amusing. She admitted she used Latisse, a prescription serum meant to grow eyelashes, on her eyebrows.

"It's a miracle. It's a product that helps your lashes grow really long," she gushed. "I was like, 'Oh, this will be a good idea to make my eyebrows fill in.' And so I used Latisse on my brows and they, like, took over my role as a judge on the 'X Factor,'" she laughed. "I mean they had an opinion of their own."

The 'Heart Attack' singer added, "It was in HD, it was so bad. I don't know what I was thinking!"
