Britney Spears celebrated her boyfriend and former agent, Jason Trawick's 40th birthday by buying him a new motorcycle and it seems he's reciprocated with a diamond ring!

The Hollywood agent is understood to have proposed to Britney on his birthday, just one week after she wrapped her highly successful Femme Fatale tour. She hinted at the news on her Twitter page. 

"OMG. Last night Jason surprised me with the one gift I've been waiting for. Can't wait to show you! SO SO SO excited!!!! Xxo"

The two began dating in 2009 after Britney's tumultuous relationship with paparazzo Adnan Ghalib. She revealed that she made the first move with Trawick, who was her agent at the time, and the two have carried on a "normal relationship."

Congrats Britney and Jason!
