A special lady came out to support Zac Efron for the premiere of his movie "That Awkward Moment" and just a hint, it wasn't ex-girlfriend Lily Collins.

According to E! News, the "Parkland" actor's good friend and former "High School Musical" costar, Ashley Tisdale came out to support the hot actor but unfortunately suffered her own awkward moment.

The "You're Always Here" singer arrived very earlier to the movie premiere which took place at the Regal Cinemas at L.A. Live Stadium 14 in Los Angeles on Monday, January 27th.

The 28-year-old arrived wearing a black sequin mini dress paired with studded heels to support her good friend but as she entered the theater she quickly realized she was the only one there.

Ashley Tisdale took to her Twitter account and shared her experience by tweeting a photo of empty seats in the theater.

Attached to the picture she wrote the caption, "#Thatawkwardmoment when you're the first person at the premiere...."

Luckily, Zac Efron, along with the rest of the movie's cast and its director, arrived shortly after.

Someone who didn't make an appearance at the movie premiere was the star's on-again, off again girlfriend Lily Collins.

"The Mortal Instruments: City of Bones" star has been keeping a low profile since the "Neighbors" actor told a Facebook fan that he was single.

Phil Collins' daughter was last spotted over the weekend on Sunset Strip posing in front of a Mexican Cantina for a photo shoot.
