Good news, Little Monsters! You've heard that Lady Gaga wants her new scent to smell like an expensive hooker (her words, not ours). Now Mother Monster has tweeted that she'll be shooting a commercial to go along with said perfume.

After the Grammys, Katy Perry was thanking her fans for putting her new song, 'Part of Me,' in the iTunes Top 10 and Jennifer Hudson was honored to pay homage to the great Whitney Houston on such a large stage.
