Miley Cyrus and ex-boyfriend Patrick Schwarzenegger bumped into each other at a birthday party held at the Blind Dragon, West Hollywood on Friday, May 29. 

They were both invited to the celebration by Bootsy Bellows owner, Markus Molinari, according to US Weekly.

Sources reported that both seemed to be avoiding each other in the party. "Patrick and Miley didn't interact. He didn't say a word to her." Miley, on the other hand, was spotted spending most of her time chatting with her friend and fellow singer Katy Perry.

According to Daily Mail, Schwarzenegger and Cyrus officially ended their relationship in April, after a 5-month affair. The big-named Hollywood celebrities faced several rumors prior to their breakup, including fighting and cheating allegations.

In the later months of their relationship, things between them got worse after the 21-year old model was spotted chilling with a bikini-clad girl in Mexico during spring break festivities.

However, Schwarzenegger denied the cheating rumors and said that the girl he was being linked to was his friend's girlfriend. In any case, it seemed that the denials fell on deaf ears as the accusations were cited as one of the main reasons why the 'Wrecking Ball' singer broke things off.

"The Mexico scandal did serious damage," a source said.  

In the aftermath of Molinari's party, Schwarzenegger's mother Maria Shriver took her son out for lunch in Brentwood, California last Sunday. They were joined by her two other children, Christina and Christopher. 

On the other hand, Miley has been rumored to have gotten back together with another ex, Australian actor Liam Hemsworth. They were spotted hanging out together after calling it quits with Schwarzenegger.

However, sources and rumors are going around that the two are just friends and are not rekindling their relationship. 

The 25-year-old 'Hunger Games' star and the singer were engaged for 15 months before officially calling it off in 2013.
