Katy Perry doesn't give good oral ... agreements according to a lawsuit from a British hair care company that wants to cut ties with the pop singer because it claims her popularity ain't what it used to be.

According to the suit ... Perry had a $4.5 million written contract to promote "ghd" (stands for "good hair day") products for two years starting in 2011. Her agent claims Katy's owed an additional $2 mil based on an oral agreement to extend her contract.

But in the docs ... the company behind "ghd", Jemella Group, insists there was never an oral agreement -- and they decided not to renew Perry's deal because market research shows Europeans just aren't that into her anymore.

Jemella says Perry's agent has been threatening to sue for the $2 mil ... so it struck first, asking the court to block team Perry from filing a lawsuit.

Katy's rep tells TMZ, "Jemella's attempt to embarrass Ms. Perry by including defamatory statements about her in a public filing is shameful." The rep says they plan to sue over the money Katy's owed if Jemella doesn't pay up.

Katy tells us, "They're backing out of the deal because of an ownership change, and just throwing shade to hide their bad faith."

While you may only have about a month to get ready for bikini season, some of Hollywood's hottest babes are always ready to go two pieces.

It was a former Disney dude buff arm battle, as "High School Musical" hunk Zac Efron, 25, flashed his tan, ripped muscles before hurting his wrist while filming his new movie in L.A. this week (left) -- while musclebound "Camp Rock" boy bander Joe Jonas, 23, pumped up his God-fearing biceps in a funny new video clip (right).

A$AP Rocky must love white chicks, 'cause he pissed off Black women everywhere -- including model Toccara Jones and rapper Trina -- by saying dark-skinned girls have no biz wearing red lipstick.

A$AP dished his makeup tips to fashion and beauty blog The Coveteur, saying ... "I feel like with the red lipstick thing, it all depends on the pair of complexion. I’m just being for real. You have to be fair skinned to get away with that."

Jones -- a Season 3 vet of "America's Next Top Model" -- tells us, "His comments show he has self-hate. Doesn't he love himself? How do you make a comment like that when you’re brown yourself?"

Trina agrees ... saying A$AP doesn't know what he's talking about, because she's seen women of all shades "look beautiful in red lip wear."

Rap's 'Baddest Bitch' added A$AP can kiss something that needs no lipstick.
