Holly turned 37 on Saturday and was flooded with well-wishes from people from across the world - including a bunch of celebrities. However, her sister Kelly's posts showed just how similar the pair are, check them out:

Holly replied: "Love you Kells.... thank you xxxx"

The presenter was also showered with love from her friends, with Spice Girl Emma Button, presenter Kate Thornton and actress Tamzin Outhwaite all keeping up a very blonde theme and sharing photos and birthday wishes.

Baby Spice Emma posted: "Happy birthday gorgeous girl. Love you to bits." alongside a photo of the pair wearing matching 'Girl Power' t shirts.

EastEnders actress Tamzin, who is the cousin of Holly's husband Dan, wrote: "Happy birthday @hollywilloughby you gorgeous woman...have a wonderful day. xxx"

Whereas Phillip Schofield shared a more emoji-filled message for the birthday girl:

On Friday's This Morning, Holly and best pal Phil joked about how she was going to be feeling rough while presenting Dancing On Ice today.

"God you're going to be rubbish on Sunday aren't you?" he asked as she sipped a glass of wine.

To which she agreed: "I'm going to be really rubbish on Sunday, no I won't I'll be fine!

"I'll just carry on."

Well, yeah, it's not like she's not even presented hungover before, is it? Who can forget the morning after the National Television Awards a couple of years back when her and Schofe hadn't even got changed out of last night's clothes?

So that's something to look forward to later on, eh?
