Daniel Radcliffe has confessed that he's a "useless" boyfriend.

The Harry Potter star is promoting his new movie The Woman in Black and opened up to British newspaper Daily Mirror about his love life.

He's currently dating production assistant Rosie Coker and says that she has no idea what she's let herself in for.

"Rosie's lovely," he gushed. "She's a wonderful, wonderful girl but far too good for me!

"I'm not an easy person to love. There are lots of times when I'm a very good boyfriend but there are times when I'm useless. I'm a mess around the house, I talk non-stop, I get obsessed with things.

"But she listens to it all, and she loves my oddness and awkwardness. She finds it cute. I guess that's love."

Daniel was also wistful about the fact that they will be apart for the most romantic day of the year.

"I haven't seen her for weeks and I won't even be back for Valentine's Day," he sighed. "I'll be home a few days later though, so I'll have to make up for lost time.

"I can't wait to see Rosie. I've got three weeks off so we can be together although I do plan to watch quite a bit of sport on TV."
