Miley Cyrus and Selena Gomez don't seem like they'll ever be friends.

The two former Disney Channel stars have been pinned against each other since they both reigned on the network with their respective shows.

Plus, the pair apparently have an ex boyfriend in common, Nick Jonas.

Cyrus also happens to be really good friends with Gomez's ex Justin Bieber, which adds further fuel to the blazing fire of drama between the two stars.

Furthermore, on screen they were even enemies on Cyrus' show, Hannah Montana. Cyrus' Hannah and Gomez's Mikayla were rival pop singers.

To add to their never-ending drama, it appears as though Cyrus mocked Gomez on Instagram.

Gomez posted a photo of herself on Instagram on Jan. 14, in which she's in a black bikini top after going for a swim and she's pouting her lips with her head slightly tilted.

Cyrus posted a similar photo on Instagram on Jan. 21, showing off her cleavage in a black lacey bra, in which she asked in the caption, "Do yiew think if I push muah t----es up I'll get mo followahhhzzzz?"

That led to Gomez's fans speculating that Cyrus was indeed mocking their idol. Cyrus fired back on Twitter on Jan. 23 quoting Nicki Minaj's rap from Bieber's Beauty and a Beat.

Gomez appears to have fired back with a little help from fellow actor and friend Brandon Smith.

Smith posted a photo on his Instagram on Jan. 24, in which he and Gomez have their tongues out, which is definitely a signature pose of Cyrus.

Smith called Gomez "family" in the caption so it's clear he's on her side with all the feuding between her and Cyrus.
