Sources close to Miley Cyrus and Liam Hemsworth are telling completely different stories on why exactly the couple broke up.

TMZ reported that people from Cyrus' side claim she tried to valiantly to save their marriage. According to them, the dealbreaker was that Hemsworth was drinking excessively and using certain drugs. Cyrus allegedly didn't want any part in it, especially since she struggled with substance abuse previously.

However, a source close to Hemsworth claims that Cyrus was unfaithful to Hemsworth.

"This is another attempt by Miley to distract from her infidelity and recent outrageous public behavior," a source told TMZ.

After news broke of their split, Cyrus was seen kissing Kaitlynn Carter while on vacation in Italy. Both Carter and Cyrus have posted photos from the vacation. Carter's ex-husband, Brody Jenner, left a since-deleted comment on Carter's picture with Cyrus that read, "hot girl summer" with a fire emoji.

Hemsworth shared that he will not make any other public statements after he shared an Instagram post announcing the split in his own words. Cyrus' rep initially announced the split with a conjoined statement.
