The former glamour model wrote that she spent time with her close family rather than have a big blowout, after recently discovering her partner Kieran Hayler had been cheating on her.
'It's the second year on the trot I've been unable to celebrate Pricey style with a cocktail - let's hope I'll have a few next year' Katie wrote in her column for Now magazine.
This time last year Katie was pregnant with Jett, her first child with builder husband Kieran Hayler, and so was unable to indulge in a big night out.
And after discovering she is six months pregnant with her and Kieran's second child last month, Katie was forced to have another quiet one to celebrate her turning 36.
Kieran Hayler revealed the full details of his affair with Katie's pal Jane Pountney over the weekend, with Katie hitting back at him on Twitter.
'@kieran0322 and jane pountney the whore were f****** all through France they been f****** in my house the whole time even when I was home.'
'@kieran0322 has confessed this today they are both lying cheating C**ts,' she added.
Last week Kieran tried to make amends with his wife of one year, writing on Twitter:
'Happy birthday to my beautiful wife @MissKatiePrice I love you with all my heart forever and always.
'….I will repair your broken heart and I am looking for the light at the end of the tunnel for our fairy tale ending! Believe in me xx'
Katie then posted a snap of several bunches of flowers all sent from Kieran on the day.
