Britney Spears and her boyfriend Jason Trawick have brushed off rumors of a split by putting on a united front during a shopping trip in Los Angeles on Wednesday.
 
The Toxic hit-maker has been dating her agent since early 2009. They were rumored to have broken up last August, only to reunite weeks later.
 
The pair's relationship came under scrutiny again this month, following reports they ended the romance after a series of arguments.

However, Spears silenced the gossip with an outing in L.A. on Monday, walking hand-in-hand with her lover during a trip to the Barney's Of New York store in Beverly Hills.
