Miley Cyrus was feeling mighty generous during a Saturday night out with two of her pals and fiancé Liam Hemsworth. The newly engaged star picked up the tab for her group after they dined at Studio City, Calif., eatery Kiwami.

Clad in a baby blue button-down top, her signature short jean shorts and tennis shoes, Cyrus kept any PDA to a minimum with her man.

"There was no holding hands or kissing," an onlooker tells PEOPLE. "The group just seemed like they were having a good time catching up."

While the source says Hemsworth was "more quiet and reserved," Cyrus was "outgoing, chatty and seemed like a lot of fun."
