A person familiar with the plans for Sunday's Super Bowl halftime show told AP that Missy Elliott is slated to make a surprise appearance during Katy Perry's performance.
The person spoke anonymously to the AP because Elliott's participation had not been announced by the NFL.
During a news conference Thursday, 30-year-old Perry hinted at Elliott's involvement in the Super Bowl act, which also will feature Lenny Kravitz.
Perry said the halftime show will include an 'old school' female singer — but did not say who that would be.
'When you hear the first ring of the chord,' Perry promised, 'I think jaws will drop and faces will melt.'
