Harry Styles is always the source of a good dating rumor. This week's possible paramour? Oh, just Gavin Rossdale's daughter Daisy Lowe.

Word is that the One Direction heartthrob is secretly dating the model. They reportedly met through mutual friends Nick Grimshaw (the pal with whom Hazza was rumored to be bisexual) and Kelly Osbourne.

The photo below is from three months ago but that's when the spark supposedly ignited.

Harry's romance resume is full of big names – Taylor Swift (bad breakup), Cara Delevingne (rumor) and Kendall Jenner (PR stunt), to name a few.

Dunno Daisy? Her dad is the Bush frontman and she dated Matt Smith of 'Doctor Who.' Word is she also dallied with British rapper Tinie Tempah, too.

If she and Hazza are engaging in a little hookage, she's robbing the cradle, since she is 24 to his 19. Rawr!

However, the 1D member did say that he is single just a week ago on 'GMA' so who knows. Maybe he and Daisy are just pals!
