Britney Spears and Jason Trawick are pulling out all the stops to celebrate their engagement.
The pair are holding a private gathering in Las Vegas with friends and family at Planet Hollywood Resort and Casino in Las Vegas tonight.
They are then expected to enjoy a big 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.
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.
He is said to have presented her with a Neil Lane featuring a round three carat stone that features pave diamonds on the band.
'It's very traditional,' an insider tells 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.
'OMG. Last night Jason surprised me with the one gift I've been waiting for,' she tweeted.
She then teased: 'Can't wait to show you! SO SO SO excited! Xxo.'
Sources told TMZ that her conservators gave marriage their stamp of approval.
He also did right by her father, Jamie Spears, by asking for his daughter's hand in marriage.
They will put a pre-nuptial agreement into effect before they tie the knot, according to sources.
Britney first started Jason in early 2009 following her tumultuous relationship with paparazzo Adnan Ghalib.
She says she 'made the first move' on Trawick, who was her then her agent.
He stepped down from that role in May this year.
They mixed business and pleasure again in September when she cast him to play her love interested in the video for her single Criminal.
