Justin Timberlake has allegedly split from Jessica Biel in order to start a new romance with Rihanna.
According to US Weekly, the 'Cry me a River' singer ended his three-year relationship with Biel almost a month ago.
A source said: "He just said he needs time apart to just experience being single again.
"She refuses to accept it and called him non-stop trying to save it. She can't imagine life without him."
Further reports have suggested that he broke off their romance for Rihanna, who he was spotted with at the MTV VMAs in New York on 13 September while Biel was in Canada shooting 'The A-Team' movie.
A separate source added: "They've been talking and texting non-stop since the VMAs.
"He's pressing her to plan another hook-up. They liked the excitement of sneaking around. She digs him and wants to date him."
However a source has told People that the couple are still together and are planning a charity climb of Mount Kilimanjaro in January.
