Cody Simpson is taken. The "They Don't Know About Us" singer is dating Gigi Hadid, multiple sources confirm to Us Weekly. The Australian star and his girlfriend -- the daughter of Real Housewives of Beverly Hills star Yolanda Foster -- have been dating for five months. (Hadid has been featured on RHOBH and has followed in her mother's modeling footsteps over the past few years.)

"They've been friends for awhile, it turned romantic this year," a source reveals to Us. "They are very adventurous and like to party with friends. It's very easy between them."

Indeed, the two were spotted holding hands while ice skating at Rockefeller Center in NYC just last month together. During the outing, Simpson, 16, held on to the rail while wearing jeans, a black t-shirt and matching coat. A smiling Hadid, 18, wore white pants, a grey t-shirt and orange jacket. The two also kept a low-profile by wearing sunglasses.

"They have a beautiful, loving relationship," a second insider says. "[It's] extraordinary at such a young age."

The "Summer Shade" singer was previously linked to Kylie Jenner in 2011.
