Demi Lovato confuses fans with fake baby bump

Demi Lovato just gave her fans a “Heart Attack.”

The 27-year-old pop star posted an Instagram selfie on Thursday in which she appeared to be very pregnant, but fans can breathe a sigh of relief, as it was a fake baby bump.

“Real or fake?” she teased in the caption,adding, “# WillandGrace #MeetJenny.”

The “bun in the oven” is just part of her costume for her upcoming role as Jenny in the “Will & Grace” revival.

Lovato announced in August that she would be guest-starring in the NBC show’s third and final season.

“You look so dang cute in polka dots!” Will & Grace” star Sean Hayes commented on the pic.

Others took to Instagram to join in on the joke.

“Mazel Tov,” Scooter Braun commented. Nikita Dragun added, “Me after Chipotle…”

Maybe Lovato isn’t expecting a baby, but she has gottenvery serious with new boyfriend Austin Wilson, who became Instagram official last week.

The two were spotted holding hands on a stroll in LA after going public with their love.
