RadarOnline.com reports that Britney Spears could be engaged by the end of this year.

Spears has been dating Jason Trawick for several years, and he will be accompanying the singer on her Femme Fatale world tour, which ends in Puerto Rico Dec. 10.

A source close to the Spears family tells RadarOnline.com the couple "discuss marriage all the time. Britney is truly in love with Jason, and, well, Jason has loved her for a very, very long time.”

The source added, “Jason adores her two sons, Sean Preston and Jayden James. Jason is planning on taking Britney on a secluded getaway once the tour wraps, and it's very likely he will pop the question at that time.”
