Christina Aguilera suffered an embarrassing wardrobe malfunction last weekend when she attended Etta James' funeral.

The singer gave an emotional performance of Etta's classic 'At Last,' but mourners may have noticed a suspicious drip down her leg. Christina appeared to have applied fake tan before hitting the stage, but left a streak down her right leg.

Clearly realising that something was dripping down her leg, Christina tried to wipe it away with her other leg and the sleeve of her jacket.

Ever the professional, Christina continued with her performance after giving a heartfelt speech, citing Etta as one of the biggest influences on her musical career.

Etta passed away on January 20 at the of 73 after suffering complications with leukemia.
