Selena Gomez gushes over her 'best friends' Steve Martin, Martin Short

Selena Gomez has nothing but love for her Only Murders in the Building costars Steve Martin and Martin Short

The 31-year-old actress took to her Instagram account and penned a touching note for the senior actors.

Posting a black-and-white photo of the trio sitting together on the set of their hit Hulu series, Selena penned: “I want to thank @stevemartinreally and Marty (who hates social media) for truly being the most kind, gentle, warm and powerful influences in my life.”

“You have shown me a level of class, intellect and humor that doesn’t seem to be easy to find anymore. You guys are truly best friends to me forever #thebear,” she added.

The tribute comes after the Single Soon hitmaker posted a picture of white roses from Steve and Martin which she received on the first day of filming season 4 of OMITB.

We're so happy to be back with you, love, Steve and Marty," a note with the flowers read.

Previously, Selena opened up about the bond she shares with her costars during an appearance on Jimmy Kimmel Live!

"Our dynamic [on-screen] is actually very truthful in a way. They're hilarious. Everything I do with them is just a fun experience,” she told Jimmy Kimmel last month.
