She may be putting on a Poker Face at the moment, but Lady Gaga must be in a foul mood today after MGA Entertainment slapped the singer with a $10 million lawsuit because the manufacturer alleges she and her management company backed out of a deal between the two sides.

MGA claims Gaga acted in "bad faith" after initially agreeing to include a voice chip with the doll and have it ready for sale by Christmas.

Now, the company believes, Gaga is attempting to delay the item's release to coincide with her new album in 2013.
