Friday March 22, 2013 04:00 PM EDT

Reunited and it feels so good for Miley Cyrus, who is "very happy" to have her fiancé back in the U.S.

Liam Hemsworth, 23, got home from his trip to Australia and Manila on Wednesday night, and the two have been inseparable," a source tells PEOPLE.

"Since Liam returned to L.A., Miley has been in the best mood. They are together, and will continue their wedding plans," the source adds of the couple, whose time apart ignited rumors they had split.

On Friday morning Cyrus, 20, dropped by Ryan Seacrest's Kiis FM show to talk about her "twerking" video that went viral this week (enjoy below!).

"Miley was in a great mood," an onlooker says, adding "she was wearing the ring," referring to the much-watched engagement ring Hemsworth gave to Cyrus when he proposed to her last May.
