Miley Cyrus and Liam Hemsworth are more than happy keeping their personal life private.
A source close to The Voice production tells ET that the couple are stronger than ever, adding that the Hunger Games star has visited his fiancee on set, spending time in craft services while the singer works.
However, the source explains that while Miley loves to interact with fans on the show, Liam is a subject she simply won't go into.
“[She] never speaks openly about Liam," the source says. "[She] keeps everything pretty under wraps between the two of them."
The couple, who met on the set of 2010's The Last Song rekindled their romance this March after calling off their engagement in 2013.
Recently, the "Wrecking Ball" singer shared the sweet gifts her fiance gave her for her 24th birthday.
