EVERY WEEKDAY MORNING, DailyEdge.ie rounds up the best of the day’s celebrity dirt – from the top to the very bottom.

#NIALLER: Niall Horan got James Corden’s face tattooed on his arse.

Until now, the Muscles from Mullingar was the only member of One Direction not festooned with tattoos like a lifer in a Russian prison. So it was only natural that he would decide to get the mug of Smithy from Gavin and Stacey inked on his left buttock.

OK, it was only temporary. But it was there for three weeks. Three weeks. Corden said:

He sent me updates every week, with a photo of my fading face on his arse saying, ‘It’s still not gone yet’.

You can see the tattoo – yes, and Niall’s bottom – here. (HuffPo)

#NOT FRIENDS: Monica and Rachel from Friends aren’t friends anymore. Like, in real life Courteney Cox and Jennifer Aniston have ceased to be pals.

Or at least good pals. Cox wasn’t at Aniston’s birthday party for fiancé Justin Theroux last weekend, and didn’t make their engagement party OR Aniston’s own last birthday party. Aniston also missed Cox’s birthday do in June.

This is devastating. COME BACK, RACHEL AND MONICA. Come back to us.

#SEXYTIME: Ashton Kutcher has explained how to be sexy. Want to hear his secret?

The sexiest thing in the entire world is being really smart. And being thoughtful and being generous. Everything else is crap. I promise you. It’s just crap that people try to sell to you to make you feel like less. So don’t buy it. Be smart. Be thoughtful and be generous.

I’ve tried this, but I’m still not a movie star. Nonsense. (ONTD)

#BELIEBERS: Yesterday, TMZ published photos of Justin Bieber naked with only a guitar covering his naughty bits.

Naturally enough, Bieber’s fans were incensed. They rang TMZ in their thousands.

But TMZ didn’t take their complaints very seriously. In fact, they merely recorded this video of their staff being mean to Beliebers on the phone:
