Brody Jenner has split from his girlfriend.
The 'Keeping Up with the Kardashians' star's four-month romance with model Bryana Holly is over and "just fizzled" out, according to Us Weekly.
The news comes just days after it was claimed they had an argument after attending the Playboy Mansion Halloween party on October 26 in Los Angeles, California.
A source told the MailOnline: "Brody and Bryana both partied at the Playboy Mansion to celebrate Halloween, something Bryana was really looking forward to, but the night ended really badly."
Brody - who only joined 'Keeping Up with the Kardashians' this season in a bid to repair his strained relationship with his father Bruce Jenner - and Bryana went public with their romance in June when the blonde beauty posted images of them during their trip to Hawaii on Instagram.
The images of the then-couple - who were pictured kissing on at Hulopo'e Beach on the island of Lanai - have now been taken down from the photo-sharing site.
The source added: "Straight away the next day both deleted each other off Instagram.
"Bryana even went as far as deleting all the photographs with Brody, including their special trip to Hawaii."
Bryana is Brody's first known girlfriend since his two-year relationship with Avril Lavigne, which ended in January 2012.
He has also enjoyed a romance with his 'The Hills' co-stars Lauren Conrad and Kristin Cavallari.
