Selena Gomez and The Weeknd can't keep their hands off each other.

Selena Gomez and The Weeknd's glamorous Italian getaway has no signs of stopping.

Although Gomez's mother, Mandy Teefey, appeared to be the one on the 24-year-old singer's mind on Monday, when she Instagrammed a cute throwback of the two. "My momma," Gomez wrote. "I sit back and think about how much she has done and shown me... it truly has blown me away. She teaches me most about life and I couldn't be luckier to have a partner like her in life."

Gomez and 26-year-old The Weeknd have been in Italy since Friday, and haven't been shy about showing PDA. The "Hands to Myself" singer even shared her first social media post featuring her new beau on Monday morning -- though she has since deleted it -- when she captioned a black-and-white video of him with a heart eyes emoji.
