Apparently the pop stars most recently decided to end their relationship last week but have since rekindled and are giving their relationship another try.
A source told website TMZ.com that 18-year-old Justin and 19-year-old Selena's current situation is tenuous and stated that they are not a "solid" couple.
The two have been dating for around a year and a half and while Disney actress Selena has maintained her squeaky clean image, Justin has been faced with some controversy recently.
Could take One Direction in a fight
Recent reports claimed that Justin may have to face jail if convicted on criminal charges for an altercation with a photographer.
Justin recently said he thinks he could take One Direction in a fight.
Although the Boyfriend hitmaker knows he couldn't beat the boy band if they all attacked him as a group, he is confident he could hold his own individually against Niall Horan, Zayn Malik, Harry Styles, Louis Tomlinson and Liam Payne.
He is quoted as saying: "I'd get my ass kicked (against all of them). But one-on-one I'd take them. I'd try a spin-kick. To the face."
