Britney Spears could be engaged by the end of the year, RadarOnline.com is exclusively reporting.

The pop icon has been dating Jason Trawick for several years, and he is accompanying her on her Femme Fatale world tour which wraps up in Puerto Rico on December 10, 2011.

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

“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.”

Britney Spears has been dishing out lap dances like candy on Halloween recently and now Howie D might be in for a treat.

The Backstreet Boy is set to join Brit’s Femme Fatale Tour on the South American leg so he can expect the same saucy treatment as her most recent opening act, Joe Jonas, who got the dance - and shock - of his life on Monday.

Wearing fishnets and a bustier, Brit gave her shy tourmate an eyeful during her concert in London when she tied Jonas to a pole and writhed all over him during the scandalous routine.

And although the naughty pop star has known Howie since they were kids, that probably won't stop her giving him the same sexy on-stage performance.

Howie told MTV News that he was excited to hit the road with the Oops I Did It Again singer. “I embraced it with open arms,” Howie said.

So far Brit Brit has also given the sexy pole dance to her boyfriend Jason Trawick, plus Lance Bass, Pauly D and some other lucky male fans. Must be a perk of the tour!

Howie D’s new solo album Back to Me is released later this month.

Sean Kingston made a surprise appearance on stage with Nicki Minaj Friday night, the first since his devastating jet ski accident.

And in a reflective mood, Kingston tweeted, "From every would there is a scar, and ever scar tells a story.  A story that says, I survived."

Kingston was in a horrific jet ski accident just two months ago and his recovery was far from certain when he was airlifted in critical condition to a Miami hospital.  His recuperation appeared to be complete last night, as he moved easily across the stage.

Minaj is out performing with Britney Spears as part of her Femme Fatale tour, and Kingston gave the headliner a Twitter shout out as well, thanking Nicki and Britney for "one kick ass concert."
