Selena Gomez suggests she and Justin Bieber are still together by posting photo of him on Twitter

Selena Gomez has hinted that she and long-term boyfriend Justin Bieber are still together by posting a photo of him on her Twitter page.

Rumours emerged last week that the young couple had split after Justin, 18, wrote the word 'Lingse' on his Instagram page, which is an anagram of single.

But now Selena, 20, has left the mysterious message: along with the new snap of Justin.

The pair first went public with their relationship in February 2011 but have busy schedules and often have to endure tough periods away from each other.

Selena has been filming a Wizards Of Waverly Place reunion special over the past few days and yesterday gave fans a sneak peek of the set.
