Exes Miley Cyrus and Patrick Schwarzenegger were stuck in an awkward situation when they both attended the same party in West Hollywood on Friday night. Various websites quote onlookers as saying that the former couple completely avoided each other.

Cyrus and Schwarzenegger both attended a birthday party for Markus Molinari, owner of the Bootsy Bellows nightclub, which was held at the karaoke bar Blind Dragon, Us Weekly writes. Cyrus spent the evening with Katy Perry and did not acknowledge the presence of her ex-boyfriend. "Patrick and Miley didn't interact. He didn't say a word to her," a source close to Cyrus told the website.

The couple broke up in April, after five months of seeing each other, when Schwarzenegger was spotted getting cozy with a bikini-clad woman during spring break in Mexico in March. Various websites reported that Cyrus did not like the fact that Schwarzenegger was having fun with other women while dating her.

Before Schwarzenegger, Cyrus dated “The Hunger Games” actor Liam Hemsworth. The pair got engaged during that time and there were rumors that they planned to get married. However, the two started spending less time with each other and finally broke up in September 2013.

Cyrus, who recently launched her Happy Hippy Foundation for the homeless and the LGBTQ (lesbian, gay, bisexual, transgender and queer) community, was also in news for her statement on her sexuality. "There are times in my life where I've had boyfriends or girlfriends. And there are times where I just love being with myself and don't want to give part of myself away to someone else. ... I think that's a new freedom for women, especially,” the “Wrecking Ball” songstress told Time magazine.

Cyrus said she is not “hiding her sexuality” from anyone but at the same time she does not want to “label herself” as anything. The songstress added that she is sure that her future “doesn't rely on having a partner." When “Keeping Up With The Kardashians” star and former Olympian Bruce Jenner declared that he is a transgender, Cyrus called him her “hero.”
