Singer shares and then quickly deletes romantic photo!

Hilary Duff has something of an on-off relationship with her estranged husband, Mike Comrie.

While the couple have not announced their reconciliation officially, they were spotted holding hands at a Halloween party, sparking rumours they are back together.

However, speculation that she is actually in a new relationship are now rampant, after she posted a photo of her with her co-star Nico Tortorella's arms wrapped around her waist. 

Hilary is starring in upcoming TV show, Younger which is due to air in the US in January 2015. 

Hilary then made thing even more confusing when she deleted what could have been argued as a totally innocent photo, from her Instagram feed altogether!

Hmm, quite suspicious…
