Supportive exes! Kaitlynn Carter took to Instagram to show her ex-girlfriend Miley Cyrus some love after she killed it at the iHeartRadio Music Festival in Las Vegas on Saturday, September 21.

“GET IT!!!!!” the Hills: New Beginnings star, 31, commented on Sunday, September 22. The former Hannah Montana star, 26,  can be seen rocking out in skin-tight leather pants with a matching bra top and gloves. She was decked in head to toe designer gold jewelry as she covered Pink Floyd and Led Zeppelin.

Kaitlynn Carter Comments Miley Cyrus Insta Post Split

After only one month of dating, In Touch confirmed Miley and the blogger called it quits. After being basically attached at the hip for the past few weeks, the two stepped out separately this for the first time on Friday, September 20 — which was the first hint they were headed for splitsville. Kaitlynn attended the Entertainment Weekly Pre-Emmys Party minus her plus one in a chic and edgy sheer lace dress.

Miley was also spotted sans the blonde beauty as she prepped for the iHeartRadio Music Festival, which she would be attending with her mom, Tish Cyrus, and her sister Brandi Cyrus.

Miley and Kaitlynn started hooking up after their splits from Liam Hemsworth and Brody Jenner, respectively. The pop star and the Aussie, 29, made their breakup public on August 10, after only eight months of marriage. Just hours later, Miley and the California girl were  spotted making out on a yacht in Italy. Kaitlynn and Brody, 36,  split on August 2 after five years together. Just one year prior, the two married in an Indonesian wedding ceremony, but their marriage was never legal because they didn’t obtain a marriage license in the United States.

Even though Miley and Kaitlynn’s romance was short-lived, the ladies were genuinely head over heels for each other. “Miley and Kaitlynn’s relationship isn’t just for show,” an insider exclusively told In Touch. “They’re genuinely in love. … Miley is so happy.” The former couple were recently spotted celebrating Kaitlynn’s birthday together where the two appeared to be “having a blast,” adding, “You’d never know [Miley] was going through a divorce. She was acting like she didn’t have a care in the world.”

Do you think these two will stay in apart or find their way back to each other?
