Miley Cyrus reportedly split from her girlfriend Kaitlynn Carter this week.

This comes after ending her marriage to Liam Hemsworth, who she has been on and off with sing they met on the set of the 2010 movie The Last Song.

And on Saturday the pop siren, who has been promoting her Charlie’s Angels song with Ariana Grande and Lana Del Rey all month, cut a lonely figure as she posed for a selfie with her dog.

Cyrus has been in Las Vegas with her mother Tish and sister Brandi.

In the new image, she wore a pair of tight, dark blue jeans and knee high beige boots with a white top and brown jacket.

‘Viva Las Vegas,’ she captioned another selfie while posting about catching a Def Leppard concert over another similar pose.

The star has about a dozen pets.

In 2012, Miley and Liam adopted Happy, a Rottweiler-beagle mix, Penny Lane (dog), and MaryJane, a pittbull. In 2013, Miley adopted Bean, a 𝚋𝚊𝚋𝚢 Chihuahua mix.

Liam adopted Tani, the mixed-breed pit bull while on a break with Miley in 2014. Miley adopted Emu (aka MuMu), the Shetland sheepdog in 2014. In 2014, Miley adopted Pig Pig but she passed away in June 2109.

Dora is a rescue dog who was technically Liam’s, but Miley treats her like her own. Miley and Liam also adopted Milky, yet another pit bull in 2015. Long-haired sisters Kiki and Lilo were adopted as kittens in 2015.

In 2015 they also adopted Shanti Om Bb in May of that same year. In July 2016, Miley and Liam rescued beagle Barbie from lab testing.  There is also a cat named Harlem.

Cyrus and Carter have reportedly ended their relationship of barely over a month, according to People.

The 26-year-old singer and the 31-year-old former wife of Brody Jenner are apparently staying close, even if their connection is no longer romantic.

‘Miley and Kaitlyn broke up,’ said a source with knowledge of the former couple. ‘They’re still friends.’

‘They’ve been friends forever and were there for each other when they were both getting separated,’ they continued, adding: ‘But they’re just not in a romantic relationship anymore.’

The sudden split came as a surprise to followers of the couple, as Miley and Kaitlynn were seen out together in Los Angeles only a week ago on September 14.

The couple had reportedly been living together in LA following their breakups.

‘They live together and are very happy. Miley is doing great. She is moving on. She seems to have no regrets. She loves being with Kaitlynn,’ a source told People at the time.

Kaitlynn initially shared vacation photos of herself aboard a yacht with Miley on August 9, only two days before the Wrecking Ball singer announced that she had separated from her husband Hemsworth, 29, whom she’d been married to since December of last year.

It was reported that Kaitlynn had broken up with Brody on August 2, though Page Six reported that their elaborate Balinese wedding hadn’t been a legally binding ceremony.

On August 11, photos were released of the two women cuddling and kissing aboard a boat, confirming the two had sparked up their own relationship.

Though the new pairing may have been a surprise, the connection between Miley and Kaitlynn wasn’t anything new.

The two had been friends for years, and they spent plenty of time together when they were married to Liam and Brody.

Their tryst reportedly took Liam by surprise. He filed for divorce from the Party In The USA singer after seeing the photos of her and Kaitlynn kissing aboard the boat.

Fierce: Miley has stayed away from the public eye in recent days, though she shared a fierce photo of herself solo that showcased her trim arms and a bit of underboob
