It's been almost two weeks since Ariana Grande's ex-boyfriend Mac Miller was found dead from a suspected drug overdose at his home in Studio City, Calif., and Breaking Celebrity News has exclusively learned that the "devastated" singer is undergoing "intense" therapy to cope with the loss.

"Ariana is taking Mac's death really rough, and her mother has been staying with her right now," a pal told Breaking Celebrity News. "She's in therapy."

As Breaking Celebrity News readers know, Grande and comedian fiance Pete Davidson were a no-show at last night's Emmy Awards ceremony, even though his hit show Saturday Night Live won best variety sketch series.

And according to the source, the "No Tears Left To Cry" singer, 25, is laying low as she recovers from the tragedy — but working behind the scenes to ensure Miller's loved ones are okay.

"Ariana has been in contact with his family, and is doing everything she can to honor him," the source added.

Although Grande, who broke up with Miller earlier this year after two years together amid his continued substance abuse, has remained quiet since Miller's tragic passing, she shared a heart-wrenching post on Instagram to let fans know she was okay.
