Girl group FIESTAR will be making their comeback on April 25 with "One More."

Today, they released a teaser photo for their upcoming comeback and showcased a more sexy look.

They were seen wearing crop tops and high waisted pants for a more feminine and sexy look.

Their agency commented, "For this new album, they went for a more classy type of sexy. They will be revealing a more upgraded image this time around."

They will release their song on April 25.

Fiestar is a five member girl group from South Korea formed by LOEN Entertainment, but due to LOEN's multi-label system they are currently under Collabodadi.

The gorup consists of multi-national members: Jei, Linzy, Hyemi and Yezi from South Korea; and Cao Lu from China. They made their debut in 2012 with their single, Vista.

They are also currently filming their own reality show Fiestar Channel in SBS MTV.

While many of the members took part in various activities before the group's formal debut, according to their agency, all of them had been training together for two years and the average training time among the members was 4 years. Chinese member Cao Lu was previously a solo singer in Mainland China after winning a 2004 CCTV sponsored singing contest. Her album, titled Cat, was released in 2005 under her former stage name, LuLu.

The main rapper of the group, Yezi, also became famous as an underground rapper even before she debuted, since she released various rap mixtapes on her account and garnered high praises before she was planned to become a member of the group.

Leader Jei did modeling for various online clothing stores and was the female lead for boy band Infinite's music video for their song "Paradise," Bongshil Sister's My Love and also for Taw's music video for Happy Hours featuring Joo and the Lifestyle. She later replaced Joo on the promotions due her being diagnosed with a bump on her throat, and became fine right after the promotions ended.

Linzy was a trainee under YG Entertainment and was originally planned to be a 2NE1 member and is also one of the trainees to be originally planned to become a member from YG's new girl group (but the idea was scrapped in 2012).

Hyemi and Jei both starred in IU's Good Day and You & I music video as backup dancers.
