Spears showed off the plain band on her left ring finger while attending son Jayden’s soccer match in L.A., sending the rumor mill into overdrive.
In December, Celebrity Fix reported that Britney and David planned to tie the knot in a New Year’s Eve wedding ceremony in Las Vegas.
The site claimed the pair would wed at the Simple Wedding Chapel, just days after the launch of her “Piece of Me” residency at Planet Hollywood.
The report was in sync with what Britney told “Extra’s” Mario Lopez earlier, saying she might consider retiring after her 96-show stint, "I might, who knows… I may have two more kids and get married… I'd like to have more kids."
Spears infamously married childhood friend Jason Alexander in Las Vegas in January 2004, but they had the marriage annulled within days.
She went on to wed Kevin Federline later that year and they had two children before splitting in 2006.
Spears met Virginia-raised lawyer Lucado nine months ago at a party. She told Ellen DeGeneres their mutual attraction was “instant.” See her gushing about her beau in the clip below.
