Love is in the air for Miley Cyrus and boyfriend Patrick Schwarzenegger.

The couple went on a dinner date Friday night with his mother Maria Shriver at Laurel Hardware in West Hollywood, according to E! News.

"They all looked like they were having a great time -- enjoying engaging conversation and laughing," an eyewitness said. "It looked like Maria and Miley got along really well."

The pop star and college student seem to be so much in love.

"I saw her put her arm on his shoulder and then he put his arm around her," the eyewitness said. "They were smiling a lot."

Another eyewitness said, "Miley and Patrick were really cute together. They look like they are genuinely in love."

Last month, Miley spent some time with Patrick's father Arnold Schwarzenegger. The actor and former governor of California joined the couple on a ski trip to Idaho.

"Arnold has embraced her with open arms," a source said at the time.

Even Patrick's uncle took a liking to the former Disney star.

"Anthony Shriver had a great time hanging out with his nephew and Miley during Art Basel," a source said after the couple traveled to Miami. "He said Miley was a lot of fun. As far as he's concerned, the family has no problem with her."

Miley's brother Braison Cyrus and Patrick's sister Christina Schwarzenegger have started dating, according to E! News. It seems like both families are getting along.

Braison and Christina met in November at Miley's 22nd birthday bash at the Beacher's Madhouse secret location by the Santa Monica Pier. The couple started dating just a month after meeting.

Christina is a 2013 graduate of Georgetown University and Braison is a singer-songwriter who is currently working on new music.

Meanwhile, Miley was spotted swimming topless with Patrick, HollywoodLife.com reported.

Reports say Schwarzenegger loves the way Miley expresses herself and has completely supported her in recent nude photo shoots.
