Miley Cyrus and Liam Hemsworth are seeking involvement in couples' therapy, PerezHilton.com reports, intensifying rumors the "We Can't Stop" star is the only one making attempts to salvage the relationship. 

A source close to the couple said a break up might be imminent because she's the only one trying to make it work.

"Miley's very committed to Liam and to making it work, but she has complained that she feels like it's always her making the effort to keep them afloat," the source told Hollywood Life.

"Notice how it's always Miley visiting Liam wherever he's working and not the other way around. Miley would love it if Liam would make the effort to fly out and surprise her or something romantic like that but she's not going to fight over it."

The source also told Hollywood Life their biggest stressor is all the time apart.

Miley Cyrus, who met up with Liam Hemsworth in Canada to visit him for a weekend getaway near his movie set, has been traveling across the world to garner more publicity for her new hit single, "We Can't Stop."

And Liam Hemsworth has been filming his newest piece, "Cut Bank," with co-star Teresa Palmer.
