POP stars 3Oh!3 looked unrecognisable from their days as teenage heartthrobs as they performed on stage.
The pair, now in their early middle ages, made an appearance at the Not Just A Punk Phase Fest in Kansas City earlier this month.

The American electro-pop duo from Boulder, Colorado, founded the group in 2004 and named it after the 303 area code.
They gained popularity in the late 2000s and early 2010s for their energetic blend of electronic, pop, and hip-hop music.
3Oh!3 is best known for their single Don’t Trust Me from their album Want, which reached number seven on the Billboard Hot 100.
Their second single, a remix of Starstrukk featuring Katy Perry, became a top ten hit in the UK, Ireland, Finland, Poland, and Australia.
They gained further popularity with the song My First Kiss, featuring Kesha, which served as the lead single from their album Streets of Gold.
The album later peaked at number seven on the Billboard 200.
However, they hit a wall with their 2013 follow-up, Omens, which received mixed reviews and ultimately fell short of expectations.
After this, the band disappeared from the public eye, except for a few sporadic performances.

"We were both going to underground hip-hop shows and stuff," Motte told Westword Magazine.
"We actually only formally met in a physics class, and then we bonded over music really quickly."
