Tatu beauties LENA KATINA and YULIA VOLKOVA scored a big international hit with their debut single ALL THE THINGS SHE SAID in February 2003, which was accompanied by a video showing the teenage singers kissing.
English singer Parks, who won the second series of UK TV talent show Fame Academy, claims Tatu's behaviour was an insult to homosexuals.
Parks fumes, "It is insulting to see Tatu acting the way they do.
"It feels like they're trying to make a bit of a joke out of being a lesbian. It's sad.
"If their music was any good then it might help, but their latest record (ALL ABOUT US) sounds exactly like the previous one."
