The star of "The Mortal Instruments" is said to be dating former Disney child actor Zac Efron.

Just last Friday, the two were spotted together after catching a movie in Hollywood. Collins and Efron were linked back in 2012 and these two had dated for a few months. Now, it seems like the daughter of Phil Collins and the High School Musical star would want another go at rekindling their romance.

Efron and Collins were seen dressed in rather casual wear and Efron seemed to be looking healthy even after his reported rehab stint just last month. Collins, who had recently split from co-actor Jamie Campbell, seemed all smiles while with the star and they seemed to be enjoying each other.

There seems to be chemistry between the two as they shared smiles as Collins got into the car of Efron where they drove off maybe to get something to eat.

It is quite odd to see Efron out with the Mortal Instruments star as the actor was seen a few nights back with his hairspray star Britanny Snow. The two have not spoken if whether they were an item or not and it seems like Efron has no intentions of settling down with any girl.

It has been years since the actor had been linked to any other girl after his split with co-star and actress Vanessa Hudgens. The two had dated for almost four years until they had decided to call it quits. Collins had dated her co-star Jamie Campbell for a year before they too decided to just be friends.

Is there a spark in the air for both Collins and Efron with each other? They do seem to be getting along just fine and both have movies of their own that are about to hit the cinemas.

What do think about these two: are they a Couple yet?
