American singer/actress Miley Cyrus celebrated her 22nd birthday with her new boyfriend Patrick Schwarzenegger at the Metropolitan Nightclub in West Hollywood.

According to a report in Hollywood Life, former fiancé Liam Hemsworth did not contact the former Disney star for her birthday.

"It's all about Patrick. She is over it with Liam," a source told the website.

"He didn't reach out or do anything for her birthday," the insider added. "He didn't call or send a message. He was only worried about The Hunger Games box office and was watching football. Miley was not on his mind or agenda this weekend."

The Hunger Games star and Cyrus met on the sets of Nicholas Sparks film The Last Song in 2009. In 2012, Hemsworth proposed to Cyrus with a 3.5-carat Neil Lane diamond ring.

The couple made their last public appearance together at the premiere of his film Paranoia at the DGA Theater in Los Angeles, before Hemsworth officially announced his split from the Wrecking Ball singer.

Meanwhile, the We Can't Stop singer shared some photos taken at her birthday party on Instagram.

Following weeks of speculation, Cyrus went public with her romance with the 21-year-old son of Arnold Schwarzenegger and Maria Shriver during the recent USC Trojans football game against the California Golden Bears by putting on a very passionate display.

Cyrus and Patrick kissed and cuddled in full view of hundreds of spectators at the Los Angeles Memorial Coliseum.

Patrick has previously talked about the Wrecking Ball singer.

"My eye, though, is set on Miley," he told Details magazine in 2011.
