Los Angeles, California - Selena Gomez has been packing on the PDA with her boyfriend Benny Blanco since they started publicly dating in December, so it's no wonder that he has a sappy pet name for her!

On Monday, the music producer posted a candid shot of the Only Murders in the Building actor to his Instagram story.

Sel, in translucent red glasses and a fuzzy headband, beams at the camera, cuddled up with a blanket and what appears to be Benny's knee.

The snap from Benny's account is captioned, "my wittle."

Could this be a pet name for Selena or a one-off inside joke for the cute couple?

Either way, it's clear that the two are no strangers to baby talk!

On February 12, Selena captioned an Instagram picture with Benny, "My bes fwend."

Selena and Benny are getting more serious every day, with Benny telling Howard Stern in May that his next life goal is to have kids.

When the radio show host said that he was "predicting marriage" for the couple, Benny answered, "You and me both."

Insiders confirmed how in love the two already were way back in January, saying that Selena was "baby crazy and openly talking about how she wants that to happen."

"He's already calling her his wife and asking her what kind of ring she wants," the source added.
