The insider told Radar, “They've split for now. Miley and Liam have a very tumultuous relationship and both are exhausted. It's a complicated relationship. The wedding is on hold, for now. It's not cancelled, but it doesn't look promising.”
The stars have been traveling separately in recent days with Miley building buzz for her new “Bangerz” album in Europe and Liam in Las Vegas with friends to watch Showtime PPV's Floyd Mayweather vs. Canelo Alvarez boxing match.
The twosome has had their ups and downs since meeting on the set of “The Last Song” in 2010 and becoming engaged in May 2012.
