Britney Spears Dons a Yellow Bikini For a Pool Day With Jayden

Britney Spears wore a bikini yesterday to swim in the pool of her Buenos Aires hotel with her sons. Jayden James and Sean Preston Federline were able to spend more time splashing around with Brit and her boyfriend Jason Trawick following a similar afternoon last week in Rio.

Britney's Femme Fatale tour moved on to Buenos Aires from Brazil, and after her Argentine show last night, Britney tweeted, "So much love — thank you Argentina!" She will be in Chile tomorrow, and Peru, Columbia, and Venezuela are up next before she moves on to Mexico and the Dominican Republic. Her last show of the year is Dec. 10 in Puerto Rico, and then Britney has two weeks to relax before celebrating Christmas with her family! Before returning to the US, though, Britney will ring in her 30th birthday on Dec. 2.
