Nice ice! Britney Spears showed off her engagement ring with new fiancé Jason Trawick at the Planet Hollywood Resort and Casino in Las Vegas


She took to her Twitter page earlier in the day to tell fans she was 'still glowing' after boyfriend Jason Trawick asked her to marry him.

And Britney Spears couldn't have looked more radiant tonight as she showed off her engagement ring while hosting a party for her former agent beau to celebrate both their engagement and his birthday.

The 30-year-old singer donned her sparkling three carat Neil Lane diamond with pride as she posed up with her new fiancé at the Planet Hollywood Resort and Casino in Las Vegas.

Earlier in the day, Britney tweeted fans: 'Still glowing! About to jump on a plane to Planet Hollywood in Vegas.

Britney and Jason will be celebrating their engagement with a private gathering at the resort, before moving on to a celebratory dinner at the Chocolate Lounge at the Sugar Factory in the Paris Hotel before carrying on the festivities at a dance party at the Chateau nightclub.

The pair looked happy and excited as they made their way into the resort for the party, Britney beaming as she was congratulated by staff and fans.

Of course, Vegas is familiar territory for the singer - it is where her 55 hour marriage to first husband Jason Alexander began and ended.

The Hollywood agent asked for the pop star's hand in marriage in Los Angeles yesterday on his 40th birthday.

'Yes, we are engaged,' Trawick told Access Hollywood today.

Talking about the Neil Lane ring, an insider told Us Weekly: 'He picked out something he knew she would love.'

'He surprised her after she gave him his gifts and after they had cake last night,' another source adds.

The 30-year-old singer, who has just wrapped her Femme Fatale tour, hinted at the news this morning on her Twitter page.

Six months later she became engaged to her backup dancer, Kevin Federline.

They wed in a surprise ceremony at a private home in Studio City, California, in 2004.

They went on to have two children together before officially divorcing in 2008.

Britney's love life has always been colourful - as a teenager she famously dated fellow former Mouseketeer and 'N Sync band member Justin Timberlake.

The pair split in March 2002 after a three-year romance that had fans and tabloids in a frenzy.

After they parted ways, Timberlake made reference to the pop star in the video clip to his hit, Cry Me a River.

The clip featured a Britney look-alike and the storyline fuelled rumours that she had cheated on him.

"[The breakup] was horrible,' Britney told People magazine.

'Very upsetting and it took a lot out of me. He was my first real love, and I doubt I'll ever be able to love anyone like that ever again.

'But I'd rather spend two days with my soulmate than the rest of my life with some guy who doesn't mean as much.'

'So it was one of those things that was really silly.'
