Grande romantic gesture: Singer Ariana and her beau Big Sean take to the stage in coordinated festive red outfits as they perform at KIIS FM's Jingle Ball

They recently returned to Los Angeles following a whirlwind trip to London for the Victoria's Secret Fashion Show.
But Ariana Grande, 21, and her boyfriend Big Sean, 26, showed no signs of jetlag as they put on a tactile display while performing at KIIS FM's Jingle Ball on Friday.
The couple stepped onto the stage at downtown Los Angeles' Staples Center in coordinated red outfits as they treated the capacity crowd to a performance of their song Best Mistake.
