Britney Spears is getting ready for her 30th birthday on Friday and will finish up a successful world tour next week – but that’s not all she’s gearing up for.
A source close to the singer tells PEOPLE that an engagement is imminent for the pop star and longtime boyfriend Jason Trawick, 39, who sources say has picked out a ring.
“They?ve been talking about marriage for a long time,” says the source. “It would be surprising if they are not engaged by the end of the year.”
Adds the source: “Britney is really looking forward to turning 30. She is having one of the best times of her life.”
