First there was Bradley Cooper's girlfriend Suki Waterhouse getting kinky with someone else.
We're not talking kisses with another man, just BFF model Cara Delevingne licking her armpit. As you do.
And now it's Rita Ora's turn to get up close and personal with a mate, namely singer Iggy Azalea.
We think Iggy was giving Rita Ora a helping hand as she was getting ready for the 2014 Met Gala, though we doubt the whole using her bum for a pillow thing was that helpful.
Now we're all for a bit of tasteful PDA, in fact we can't get enough of cute celebrity couples cuddling each other on the red carpet.
However, there is such a thing as a step too far, and a tongue licking a sweaty armpit is it.
No matter how much you love your girlfriends, there is no reason for their tongue to be that close to you.
What do you think about friend PDAs? Tell us @handbagcom
SUKI WATERHOUSE HAS A 'BIG ARSE'...APPARENTLY
IS THIS THE QUIRKIEST CELEB COUPLE?
