While Zayn was partying, his former bandmates were enjoying 1D's half-decade milestone.
On the eve of One Direction's fifth anniversary, former band member Zayn Malik was spotted partying at the Los Angeles nightclub 1 OAK, and ET has an exclusive look at the singer's night out, with video courtesy of lmnola.com.
An eyewitness tells ET that the 22-year-old left the venue with a couple of friends around 2:30 a.m., and was seen sticking his tongue out at photographers outside the club. This is the first time Zayn has been spotted in L.A. since he quit One Direction in March.

On Wednesday, some members of One Direction – who jetted out of L.A. the night before – took to Instagram to thank for their fans for all the support over the last half-decade as their fifth anniversary approached, with Harry Styles writing, "to you who support us, in any way, thank you. We wouldn't be here without you."
Edmonton was a lot of fun last night. Thank you for being there. Thank you for having us. Hope you enjoyed it. H
