Demi Lovato knows how to tease us!

The singer took to Instagram yesterday to share a photo and video of herself rocking a huge baby bump.

“Real or fake?” she captioned the photo with the hashtags #WillandGrace and #MeetJenny.”

Demi is joining the final season of Will and Grace in August, and her character, Jenny, has been described as a “tough, guarded woman who comes into Will’s life in an unexpected way.”

Hmm… could it be through surrogacy? We’ll just have to wait and find out!
