Emma Watson new boyfriend. Just who is Johnny Simmons? We reveal 10 things you need to know about Emma Watson's new boyfriend. If he's good enough for Emma Watson, he's good enough for us!Emma is one of Britain's most eligible, richest and prettiest young actresses but until now she's been pretty unlucky in love. Thankfully it looks like that's all changed due to Emma's handsome new co-star, American Johnny Simmons.

The cute couple hooked up on the set of their upcoming film The Perks Of Being A Wallflower. Johnny's good looks and solid performances have drawn comparisons to the late River Phoenix, but what else do we know about him?

Things you need to know about Johnny Simmons...
1. Johnny was born in Alabama in America's deep south and is 24, three years older than our Em.
2. Emma and Johnny (we can't decide if their celebrity nickname should be Emmy or Jomma?) got close as they bonded on the set of The Perks Of Being A Wallflower in Pittsburgh and the toned twosome were even spotted working out together. The couple that sweats together...

3. His first big break was in Evan Almighty playing Steve Carell's son. He also starred in Scott Pilgrim vs The World (playing 'Young Neil', Scott's replacement in the band) and was Dave the pet store manager in Hotel For Dogs.

4. Johnny is used to working with hot co-stars - he was in Jennifer's Body with Megan Fox and Amanda Seyfried. How's that for a double whammy? Not only that, but he got to snog Megan and have a sex scene with Amanda!

5. He's starring in upcoming flick 21 Jump Street, the remake of the undercover cop show that propelled Johnny Depp to fame in the 80s. He's also set to play a love interest for Rachel Bilson in the teen comedy The To Do List.
6. Johnny lives in a celeb-filled neighbourhood in the Hollywood Hills; his housemates are wannabe starlets Emma Ludbrook and Brittney Chavez.
7. Johnny is a good mummy's boy and was so worried about his sex scene in Jennifer's Body that he didn't tell his parents about it for ages, and eventually forbade them from watching the film. "I told my mom and dad not to go see it," he said. "Your mom doesn't want to know you're having sex, much less see it. So she's going to go watch me having simulated sex?"

8. But he can be a bad boy too - Johnny has had a couple of brushes with the law, but they're minor things that wouldn't even turn heads in Blighty. He's been stopped for speeding (shock!) and arrested for underage possession of alcohol (gasp!). He pleaded guilty and was fined $500.

9. In The Perks Of Being A Wallflower, Emma plays saucy Sam, a streetwise girl who lures her friends into a world of sex and drugs. Johnny plays clean-cut all-American sports star Brad.

10. Johnny has already met his new girlfriend's parents and has spent a few weeks in London, shacked up with Emma in the attic of her dad's place and checking out famous sights like St Paul's and Big Ben.
