Demi Lovato has struck again in the
ongoing "sleeping selfie" war with her longtime boyfriend Wilmer Valderrama.
The "Cool for the Summer" singer
took to Instagram on Monday to share a pic of the couple catching some shut-eye in bed with their adorable little puppy,
"Slept in today so I didn't post my [#NoMakeupMonday] picture, BUT I thought I'd make it up now with a cute/sneaky family photo," Lovato captioned the sweet snapshot.

sharing photos of each other in the midst of peaceful slumber for months.
The 23-year-old singer started the exchange in January when she posted a photo of Valderrama sleeping with his head on her stomach, and sharing, "I'm the luckiest woman in the world."
