K-pop singers Sangchu of the group Mighty Mouth and Se7en and have released the receipts from their numerous trips to massage parlors to South Korea's Ministry of Defense, the website allkpop reports.

The move is reportedly an effort by the two celebrity soldiers to prove they visited the establishments, known for providing erotic services, for purely medical reasons.

"Sangchu and Se7en submitted all receipts from their visits to massage shops prior and after enlistment to prove that they entered the massage parlor for treatment purposes during the Ministry of Defense's investigation into celebrity soldiers," a Ministry of Defense spokesperson told the publication Sports Seoul.

"The receipts were provided by proper massage shops."

The army spokesperson admitted that the situation is awkward.

"Although it was to prove that the visit to the massage parlor was for treatment purposes, this situation of having to even submit receipts is unfortunate," the spokesperson said.

The announcement that the two stars released their receipts comes on the heels of yesterday's report in Kuki News that they had received $1,800 from the CEO of Mighty Mouth's record label YMC Entertainment, Tae Jin Ah, to pay for their massage parlor visits.

Although the Ministry of Defense claimed to still be looking into it, a representative from the Ministry of Defense claims there doesn't appear to be anything wrong.

"We haven't confirmed how they received the check," said a Ministry of Defense rep. "If they say they got it as a friend, there is nothing problematic."

Last month, Sangchu and Se7en received a 10-day sentence in military jail, after a camera crew from the news program "Scene 21" caught them entering a massage parlor known for providing erotic services after curfew last month.

Five other active recruits previously serving as PR agents were sentenced to four-day incarceration at the military prison or "guardhouse" for using cellphones in the "Scene 21" footage, according to the Korea Star Daily.

The "Scene 21" footage rocked the country's Defense Media Agency, eventually leading to the elimination of the agency's Promotional Support Brigade, a longtime bastion for celebrity recruits, after its PR agents were filmed wandering the streets after curfew out of uniform and purchasing alcohol at 2 a.m., all after performing at an army-sanctioned concert to mark the 63rd anniversary of the Korean War.

Of the 12 celebrity soldiers that were enlisted in the Promotional Support Brigade at the time of its disbandment last month, the seven that served military sentences, including Se7en, Sangchu and the actor Lee Jun Hyuk, will be relocated to the front line, according to the website TENASIA.
