LOS ANGELES, July 9 (UPI) -- Miley Cyrus and Mike Will Made-It have reportedly been dating since 2013.

Sources told Us Weekly the 21-year-old singer and the 25-year-old producer have been seeing each other in secret since Cyrus ended her engagement to Liam Hemsworth in September of last year.

"Everybody in her circle knows they've been together this whole time," said the insider.

Another source said the couple was "pretty serious" and that Will is considered "part of the family" by the singer's mom Tish Cyrus.

Reports that Cyrus and Will were a couple began in September, of 2013, but were overshadowed by Cyrus' multiple outings with Twilight hunk Kellan Lutz.

Cyrus and Will worked together in several tracks of the singer's fourth studio album, Bangerz. According to Us Weekly, Cyrus was seen "grinding" on the producer and kissing his neck at the album's release party in October 2013.
