Fifth Harmony's member Camila Cabello and Austin Mahone have been rumored to be dating and now she confirms that it's true. The 17-year-old singer admitted to dating the "Mmm Yeah" singer when her group appeared in Monday, November 3 episode of "Watch What Happens! Live".

In the Monday episode, host Andy Cohen asked the ladies about their love stories. "Have you ever snagged any 1D guys?" he asked, to which they answered, "No." He then asked, "Hold on, who's the Mahonie girlfriend?" Cabello slowly raised her hand while other members cheered.

"We've known each other for a really long time, like a year and a half now, like on 'X Factor' was when we first [met]," Camilla said.

Following Cabello's confession, Mahone took to Twitter on Tuesday to send a cheeky tweet to his fans. "Like you guys didn't know already," he wrote, adding the post with a smirking emoji.

Mahone, who has been touring with Fifth Harmony, The Vamps and Shawn Mendes, talked about working with the girls in an interview with Fuse.tv in August. "They're crazy," he said with a laugh. "I enjoy hanging out with Fifth Harmony. We'll go see a movie on an off day. Or we'll just play basketball together or ping pong, just chill. They're talented ... and they're beautiful."
