Demi Lovato spearheaded Selena Gomez and Justin Bieber reunion?

Demi Lovato "spearheaded" Selena Gomez's reunion with Justin Bieber.

The pair - who dated for two years until breaking up at the start of 2013 - have been spending more time together fueling speculation that they've reconciled.

Selena's pal Demi - who developed a close friendship with the singer after working together on the set of 'Barney & Friends' in 2002 - is taking some time off and has encouraged the brunette beauty, who is suffering from autoimmune condition lupus, to do the same and spend it "with her family and Justin".

A source told Hollywoodlife.com: "There is zero time table to return to concerts or movies. She is enjoying her time away from work and spending it with her family and Justin. This was spearheaded not only over her lupus situation but the more she has been talking to Demi Lovato who is on her own break really made Selena take a look at her life and realize what is important and that is to enjoy some normality while she is young."

Justin and Selena recently posted an intimate snap on Instagram of them together and are also said to have spent New Year together in Mexico and were pictured riding Segways near his house in Calabasas, California.
