Miley Cyrus has reportedly been dating music producer Mike Will Made-It for nearly a year. The report from Us Weekly confirms rumors that began last September.

"Everybody in her circle knows they've been together this whole time," a source close to the singer tells Us. And it is not just a casual relationship. Another source says the pair is “pretty serious,” and Cyrus’s mom Tish “says he’s part of the family.” At a party for the BET Awards last month, Cyrus and Mike, who has produced beats for artists such as Rihanna, 2 Chainz, Lil’ Wayne, and Ciara were allegedly “all over each other.” The 23-year-old also produced Cyrus’ hit song, “We Can’t Stop.” Speculation that the two were an item began last year, shortly after Cyrus’s ex-fiancé, Liam Hemsworth, was seen out with 23-year-old Mexican actress Eliza Gonzalez.

The rumors only heightened after famed photographer Terry Richardson posted pictures on his site from a sultry shoot he did with Cyrus and Mike. The 20-year-old singer, in a cropped white tank top and underwear, poses with Will as he holds her around the waist and she sticks out her tongue.

Hemsworth proposed to Cyrus in May 2012 with a 3.5-carat diamond ring, reportedly worth $250,000. They began dating in 2009 after co-starring in the film “The Last Song.” They split last September. Ironically, he recently opened up about his relationship with the pop star while in Italy. According to the New York Post, Hemsworth told his friends that the two had a “powerful connection.”
