Last week it seemed as though Miley Cyrus was mocking her pal Justin Bieber on Instagram.

Miley Cyrus Protests Nipple Censorship Once Again

On Wednesday, April 15, the 22-year-old singer shared a picture of a recent magazine cover that claimed the same guy impregnated her and her frenemy Selena Gomez.

Cyrus claimed in her caption for the photo that Bieber is the responsible male party for their supposed pregnancies.

 And by the same man we mean @justinbieber

Miley Cyrus Hits The Studio For A Weekend Session With Mike WiLL Made-It

On Thursday of last week, Hollywood Life reported that the "We Can't Stop" singer was using this rumor to rile up her boyfriend Patrick Schwarzenegger especially after his supposed cheating scandal during his Cabo spring break trip.

A source dished that Schwarzenegger instantly knew the pregnancy story was "ridiculous" especially after what he has recently gone through in the media with his spring break trip, but his girlfriend apparently won't let this pregnancy rumor die.

"He knows what it's all about when stories come out like this and he is trying to not pay attention to it. He saw it, thought it was stupid, and forgot about it almost instantly," the source revealed, adding, "She's using it as a joke against Patrick to torment him."

"Miley's having a few good laughs over all of this and she thinks it's fun to add Patrick to it," the source said.

The entertainment site revealed in another report last Thursday exactly what Cyrus is apparently saying that's annoying her beau.

"Miley's been going as far as saying that Patrick should adopt the child and that he should practice changing diapers," the source shared, which is apparently making Schwarzenegger uncomfortable.

He's trying to act like her behavior about this rumor isn't bothering him, but it actually is.
