Selena Gomez and Justin Bieber broke up earlier in January reportedly because the "Boyfriend" singer got intimate with a nursing student in California, according to a source. 

Gomez allegedly ended her relationship with Bieber because of Milyn "Mimi" Jenson, who went to Bieber's home in Calabasas in December where the 18-year-old then performed sexual acts on her. 

"Justin surprised [Mimi] by saying, 'I want to know if you taste good.' He started kissing her cheek and ear and neck and then her whole body," the source said.

Bieber never took off his clothes, the source added, but he disrobed Jenson and began kissing her before she got scared and left. 

She may have ended things with Bieber earlier this month but Gomez is reportedly not planning on staying single for much longer. A friend close to the singer told HollywoodLife.com that the 20-year-old "Who Says" singer is looking for a new boyfriend to help her get over Bieber. 

"Selena is flirting with as many hot guys as she can right now because she's trying to get the last few years of her life back," the source said. "Justin had money and fancy sh*t, but she's hot as hell and wants to find a good guy.

"He was just a little boy and she needs a man, so yeah, she will go on a ton of dates and be happy and forget about Justin." 

Gomez performed at the UNICEF concert in New York City on Jan. 19 and sang break up songs rumored to be directed toward Bieber. She sang a rendition of Taylor Swift's "I Knew You Were Trouble" and Justin Timberlake's "Cry Me a River," in which she changed the lyrics so that it would cater to a woman's perspective.

She said to the audience about Timberlake's song, "I've been through a lot the last couple of months. It's been sad and cool, but interesting. This song definitely speaks to me."
