Are wedding bells finally ringing for Britney Spears and Jason Trawick?

Britney's BF spent Monday afternoon at the Mouawad high-end jewelry showroom in Los Angeles. A source tells X17online that Jason, 39, was spotted chatting with jeweler Pascal Mouaward around 1 p.m. They spent an hour talking about engagement rings for Britney, 29.

"They discussed diamonds from the Mouawad private collection. It's Jason's first visit with Pascal," the source tells X17online exclusively.

It looks like Brit is headed to the altar again -- congrats, Queen B!!!
