We already know Lenny Kravitz is joining Katy Perry during the Super Bowl halftime show on Sunday, but it’s now rumored Missy Elliot could join them as well as a surprise guest.

During a press conference on Thursday about her upcoming performance, Perry hinted an "old school" singer would make an appearance during the show.

The Hollywood Reporter reports she did say, "When you hear the first ring of the chord. I think jaws will drop and faces will melt."

Earlier this month, Perry confirmed Kravitz would be just one of the special guests joining her for the show.

She said at the time that the Strut singer has “so much style and a certain, how do you say,je ne sais quoi…he’s the king of cool," adding, "He’s the coolest. He’s the king of cool. He’s going to make me so much cooler that day.”

Special performers that have surprised viewers in the past include Slash and Usher.

In 2011, Elliott was featured on Perry’s remix of “Last Friday Night (T.G.I.F.)"
