Christina Aguilera Leg Drip Photo Grosses Out Neil Patrick Harris On 'The Talk' (VIDEO)

It's becoming increasingly rare for "The Voice" host Christina Aguilera to get through a high-profile performance without suffering some type of weird gaffe. She fell down after performing at the Grammy Awards and and fumbled the lyrics of the National Anthem before the Super Bowl. Now, a photo taken during her performance at Etta James' funeral, in which a brown liquid appears to drip down the singer's right leg, has become Aguilera's latest viral embarrassment.

While Aguilera's reps have claimed that the liquid was self-tanner, onlookers, including the ladies of "The Talk," (weekdays on CBS) have come up with a variety of other theories to explain the singer's "hot messy-ness."

Aisha Tyler sympathized with Aguilera. "Everybody's run out of the movie theatre with a sweatshirt around their waist... it could be that she's having her monthly visitor," she suggested.

Guest Neil Patrick Harris had the strongest reaction. "I was watching backstage, I was hoping it was runs in her stockings. And I was dry-heaving as I was watching. It's awful. Could it not have been clear? It would have been so much easier to explain," he joked, before fake-gagging into his coffee cup.
