The two young actors broke up in December

Zac
Efron
has been spotted paying a visit to ex-girlfriend Vanessa Hudgens‘s Los Angeles home.

The High School Musical couple split in December but Zac was spotted driving his black Audi straight into Vanessa‘s garage on Tuesday.

He stayed ‘quite a while’ at the property, sparking speculation that the pair may be giving their romance another chance.

The young actors’ separation after a three-year relationship, amid rumours they’d ‘grown up and grown apart’, surprised many fans.

‘They are 100% still good friends,’ a source
told People at the time of the break-up.

Zac, 23, and Vanessa, 22, started
dating in 2006.
