Well we're no stranger to Lady Gaga's boobs --but last night we almost got more than a peek at the singer's nips by accident. Oops! Poor Gaga, just when she's trying to class it up like a lady -- out pop the boobs!

The "Applause" singer's plunging dress revealed more than was intended when she left an Emmys after party at St. Vibiana's Cathedral in downtown Los Angeles on Sunday night.

Gaga, who makes her TV debut in the upcoming season of FX's American Horror Story: Hotel, wore a glamorous (but not-so secure) white gown for the festive bash. We caught the superstar as she left the glittering soiree in her Rolls Royce.

Earlier in the night, Gaga presented an Emmy Award to Richard Jenkins and made headlines for her understated Brandon Maxwell frock. We love this selection for her -- Lady G knows how to steal the show, but we like that she understood that last night wasn't her show to steal and kept her style toned down.

From meat dress to bubble outfits and futuristic frocks, Mother Monster's tried almost every out-of-this world look. But what she hasn't really done is demure and dignified. We love her in these glamorous old Hollywood styles. Hopefully there will be less blood dresses and more glam gowns in Gaga's future!
