According to Radar Online, "Kristina is a "secret hook-up" who Justin has been having "casual" relations with for some time." The mystery woman came into the picture after the egg throwing incident. Justin had a tiff with Selena who was allegedly present at his Calabasas, California home at the time of the incident. She left Justin's house furiously with a group of friends, the website reports, citing some sources.

The "Baby" hitmaker then reportedly invited "Kristina" and another female friend Lyn to his house where his friend Lil Za was also present. "Lil Za hooked up Kristina's friend Lynn while Justin got it on with Kristina. The party raged on," said the source, according to Web site.

It was that night on January 9 when Bieber's neighbour, Jeffrey Schwartz, called for cops after Selena Gomez left at around 7:30 PM. Bieber started throwing eggs at his front door. Police arrested Lil Za for possession of drugs but Justin remained unharmed.

Selena found out about the entire incident much later and also found out about the presence of Kristina in Bieber's house. When the "Come and Get It" star confronted Justin through a text message he simply became furious and did not answer anything related to Kristina.

"Nah. Go f*** someone else. Keep that talentless p**** away from me!," was Justin's nasty reply to his on and off girlfriend since 2011.

Selena remains unfazed after the incident and is busy promoting her latest movie "Rudderless" at the Sundance Film Festival. "Rudderless" will be premiered on Friday as Sundance's' wrapping-up night film.
