Miley Cyrus' famous family is "skeptical" over the singer's budding romance with rebound gal pal Kaitlynn Carter, RadarOnline.com has exclusively learned.
As Radar readers know, Miley, 26, and her The Hills star fling, 30, went out to lunch with Miley's mom Tish this past weekend in Los Angeles — just one week after Miley announced her shocking split from husband Liam Hemsworth.
"Tish doesn't know what to believe, because she is hearing from Liam that Miley and Kaitlynn were hooking up while they were both married," a source close to the Cyrus family told Radar.
"She has to support Miley regardless though, and Miley is now telling her mom they are serious. It is all just way too much, too fast."
They also believe Kaitlynn could be dating the superstar for publicity, the source claimed:
"Everyone thinks that Kaitlynn is using her, and it is just a matter of time before Miley sees it!"
As Radar previously reported, Miley and Kaitlynn were caught kissing during a romantic getaway to Lake Como, Italy earlier this month. After the photos surfaced, Miley and Liam finally confirmed their eight-month marriage was over.
