Miley Cyrus whirlwind romance with Kaitlynn Carter which began after she pulled the plug on her marriage to Liam Hemsworth, reportedly ended because they were moving too fast.

Recall that the singer who announced her separation from Liam Hemsworth in August, immediately started dating Kaitlynn Carter, broke up with her two weeks ago and then was seen making out with Cody Simpson on October 4 in Los Angeles.

The two women who were practically inseperable "got along like a house on fire," and before long they were living together and there was even talk of marriage.

Insiders however told TMZ that Miley suddenly realized she doesn't want to commit to a relationship with the actress hence their breakup.

It was further gathered that Kaitlynn is not bothered about their breakup and her romance with Cody Simpson, but only worried about her ex-girlfriend's well-being.
