Jenny McCarthy and husband Donnie Wahlberg keep their love hot with actual flames.

The couple appeared on “Good Morning America” Wednesday to discuss their A&E show “Donnie Loves Jenny.” “GMA” played a clip from the third season, slated to premiere 9 p.m. Wednesday, that showed McCarthy helping Wahlberg top a Portillo’s beef sandwich.

“Best beef sandwiches in Chicago,” McCarthy declares before the sandwich wrapping catches fire.

The new season will show McCarthy and Wahlberg settling into life in St. Charles.

The couple also announced on “GMA” that Wahlberg will perform a solo show June 2 at the Arcada Theatre in St. Charles for McCarthy’s autism charity Generation Rescue.

Tickets are scheduled to go on sale April 2, McCarthy said.

“We’ll probably shoot for the show,” Wahlberg said.
