Mariah embarrasses smooch red carpet

You'd have thought that these two would have mastered the art of a public kiss by now.

Mariah Carey draped herself all over husband Nick Cannon on the red carpet yesterday as they engaged in yet another nauseating public show of affection.

But unfortunately for the diva, Cannon looked as though he wanted the smooch to be over and done with as quickly as possible.

The couple were attending a special screening of the first ever TeenNick Halo Awards at the Newseum in Washington D.C. last night, and stopped to pose for the cameras as they arrived.

Mariah, 39, clearly proud of her husband, who is the the chairman of Nickelodeon's TeenNick network and creator of the awards, decided to reward him with a big smooch.

She was being interviewed by the talk show queen when Cannon joined her and gave her a peck on the cheek.

After was scolded by Oprah for being boring, he picked her up and bent her over, as she cried, 'don't drop me!'

He then pulled her up to give her a full-on exaggerated smooch before she pushed him away.
