U.K. urban stars JLS and Tinie Tempah were the major winners at the 2010 MOBO Awards, walking away with two prizes each.

Boy band JLS, who were runners up in the 2008 series of Simon Cowell's music talent show "The X Factor," won best U.K. act and best album for its self-titled debut, released on Epic Records/Sony Music Entertainment.

The four-piece also provided one of the standout live performances of the night when they collaborated with Travie McCoy for a rousing rendition of "Billionaire," with JLS taking over vocal duties from the absent Bruno Mars.

"Winning a MOBO Award is so extra special for us because MOBO celebrates diversity in music and it's important for us to be here tonight," band member Oritsé Williams told the audience at Liverpool's Echo Arena, where the ceremony was held last night (Oct. 20).

London-based rapper Tinie Tempah, who led the nominations going into the event, won awards for best newcomer and best video for "Frisky" featuring Labrinth. Tempah's debut studio set "Disc-overy," (Parlophone/EMI), which includes the U.K. No. 1 singles "Pass Out" and "Written In The Stars," topped the British album charts when it was released earlier this month.

"Last year I was here as a fan and spectator watching my friends pick up awards, so it's nice to be here, to finally be nominated and to have finally won something," said Tempah, real name Patrick Ogwugu.

Other big winners on the night were Plan B, who won best U.K. R&B/soul act, and former multiple MOBO winners N-Dubz, who won best U.K. act and best album (for "Uncle B" released on All Around The World/Universal) in 2009. This year the hip-hop/R&B trio, who recently inked a U.S. label deal with Island Def Jam, took home the award for best song for "Playing With Fire," featuring Mr. Hudson.

U.S. Plans For Professor Green

Virgin-signed British rapper Professor Green was named best U.K. hip-hop and grime act, having also been nominated in the best newcomer and best song categories.

"I wasn't expecting that at all," an elated Green tells Billboard.biz. "To be nominated for three and actually walk away with one is wicked," continued the London-based rapper, who added that he plans to play his first U.S. shows early next year and is currently eying a one-off collaboration with Travie McCoy.

"Travie is a good friend of mine," stated Green, whose real name is Stephen Manderson. "I toured with him and Gym Class Heroes years ago and we've always kept in touch, so we're definitely going to make some music in the future. We were talking about it again today. We're going to go and party tonight and then make it happen."

Green says he also intends to collaborate with Tinie Tempah on an "old school, dirty New York sounding hip-hop track," as soon as their schedules permit.

"Me and Tinie have been talking about it for ages and we just recently got sent a beat from [U.K. producer] Labrinth that he wants us to jump on. But we've both said that we're not going to do it unless we're in the studio at the same time and trying to get us two in the same place is impossible at the moment. But it's definitely going to happen and when it does it's going to be epic," said Green, who provided another of the night's live highlights when he performed his upcoming U.K. single "Monster" supported by a troupe of backing dancers dressed as zombies

Jermaine Jackson, who had earlier presented Green his award, looked on approvingly throughout the playful homage to Michael Jackson's "Thriller" video.

U.K. Acts In The Spotlight

The MOBO Awards were set up in 1996 to recognize British urban artists and music but have been heavily criticized in the past for an over reliance on big name American acts and no shows from nominated or award-winning artists. That was not, however, the case for this year's 15th anniversary celebrations with the dominance of home-grown acts such as Tinie Tempah, JLS and Professor Green reflecting the strong performance of U.K. urban artists in 2010, both in the U.K. and North America where Taio Cruz and Jay Sean have topped the Billboard Hot 100.

Nelly was one of the few big name U.S. acts to attend this year's ceremony, where he performed his forthcoming single "Just A Dream." Eminem won best international act but was not present to collect the award.

Other live performances on the night included Mark Ronson and the Business Intl, N-Dubz, Jay Sean, Tinchy Stryder and Alesha Dixon, who also co-hosted the event alongside U.K. radio and TV personality Reggie Yates. Tinie Tempah, meanwhile, received one of the biggest receptions of the night for a roof-raising run through his U.K. No. 1 "Pass Out."

Trinidad-born soul singer Billy Ocean, whose catalog includes Grammy Award winner "Caribbean Queen" and ""When The Going Gets Tough, The Tough Get Going" won the MOBO lifetime achievement award.

"Tonight is a beautiful night," a clearly touched Ocean told the audience.

"I find is easier to sing than to give a speech but I'd like to say congratulations to MOBO for the [past] 15 years. At least now I'd like to think that black artists like myself, or all artists, get the support that is needed," Ocean went on to say.
