Though they originally debuted as a side-project from three members of the K-pop girl group After School back in 2010, Orange Caramel have been red hot recently.

The music video for their new single "Catallena," released on March 11, has already received over 1.4 million YouTube views.

On Monday's episode of the Korean Broadcasting System radio show "2 O'Clock With Jo Jung Chi And Harim," the three Orange Caramel band members Raina, Nana and Lizzy compared themselves to another group who took off all of a sudden, the viral video sensation Crayon Pop.

"We want to be wild and crazy like Crayon Pop," Lizzy said, responding to a question about which group Orange Caramel saw as their main rival.

Yet, according to Raina, their band gets lopped in with Crayon Pop whether they like it or not.

"We're often mentioned alongside Crayon Pop in news headlines," she said.

"We never thought of them as our rivals, but I guess people put us side-by-side because we have similar concepts."

Lizzy added that though she and her bandmates have crossed paths with Crayon Pop, who are slated to open for Lady Gaga during her North American tour this summer, they aren't close.

"We met the Crayon Pop members once before, but we don't know them personally," she said.

The ladies also discussed their social lives.

"It's been more than 11 months [since I've been in a relationship], almost a year," Lizzy said. "I've asked for people to set me up on blind dates during our promotional appearances, but no one really introduces me to anyone."

The other two members of Orange Caramel also admitted to having limited dating experience as of late.

"It's been a while," Nana said. "It's hard to date since we're busy with the band."
