Selena Gomez "has no respect" for Miley Cyrus following her recent Bangerz Tour stint-she performed alongside a cardboard cutout of Justin Bieber's ex-girlfriend while singing her "FU" track."

Will she retaliate with a pregnant rumors diss?

"Selena already knows that Miley will do anything for attention even if it means dissing other people," a source told Hollywood Life.

 "Selena would never do what Miley did and doesn't really have any respect for her in the first place. She thinks Miley's number one priority in life is getting attention and she actually feels sorry for her!"

Miley Cyrus was featured topless and in underwear in recently-released Bangerz Tour pictures on Twitter and Instagram-Liam Hemsworth's break up may have silenced rumors she was pregnant.

The "Wrecking Ball" singer also posted pictures of herself drinking Vodka on Twitter and Instagram, dispelling rumors she may be pregnant as she performs her Bangerz Tour concerts.

Two weeks ago, Miley Cyrus allegedly asked her father Billy Ray Cyrus to turn down an offer for a family reality television series, Perez Hilton reports.

"Billy Ray has turned down what must be his sixth reality show offer in the last four years because Miley has been very strict with her parents about not doing them, even though they have been offered a fortune by all the big players, including Bravo, Lifetime and E, to open up their home to cameras...Miley would much rather do a Christmas special or a concert at the Hollywood Bowl with her dad rather than watch him embarrass himself like Bruce Jenner on TV every week..." a source close to Liam Hemsworth's break up told the site.

"Ever since Miley broke away financially from her parents, she's had to watch their incomes plateau while hers has skyrocketed, and so in the last three months she revisited the reality show idea with her dad...But ultimately, she was very thankful they came to an understanding together that it would be a bad idea. Miley is a student of the mistakes of the people who have come before her, and she always thought Britney Spears' decision to do a reality show was the beginning of her downfall...For now, Miley doesn't want herself or her parents becoming reality TV bottom feeders. Billy Ray agrees with her and it seems to have helped their relationship."
