Last night came down to a battle between the Banana Split Duo and the Queen of Hearts on ‘TMS.’

The Queen of Hearts performed a duet with judge Nicole Scherzinger.

The Banana Split duo performed a duet with judge Robin Thicke.

In the end, the Banana Split duo was chosen for elimination.

Scherzinger, Jenny McCarthy-Wahlberg, and Ken Jeong all got their guesses correct.

They guessed it was “American Idol” alum Katharine McPhee and her husband, David Foster.

McPhee said she was shocked Robin didn’t guess them, because Foster knew Robin since he was a baby.

She also credited Foster with “discovering” Nicole Scherzinger.

McPhee added that she was “very upset” to lose another Fox singing competition.
