Janet Jackson brought down the house on last night’s American Idol finale with a three-song performance that reminded many viewers why her brother Michael gave her the nickname “Dunk.”

After leading off with the ballads “Again” and “Nothing” (from Why Did I Get Married Too?), Janet revealed a skin tight black catsuit that highlighted all of her curvy assets (pun definitely intended).

Watch Janet’s performance below. (Things get really interesting around 5:08)
