But while she made a point of sending love to her fans, she ignored Kieran's happy birthday message.
The model celebrated her 36th birthday today (22 May) surrounded by her nearest and dearest – but it appears they weren't the only ones sending her love.
Katie took to Twitter to say: "Thank you for all my birthday wishes and for the flowers I've been receiving through the day at homexxxxx."
It marked Katie's first public comment since 7 May when she discovered husband Kieran had been having an affair with her close friend Jane Pountney.
After Katie's sister Sophie raised suspicions about Kieran and Jane's relationship, it was on 7 May that the truth was finally confirmed and Katie vowed to divorce her cheating man.

A heartbroken Katie posted a flurry of tweets branding Kieran "disgusting" – especially as she is currently six months pregnant with his second child.
Their first son, Jett, was born last summer.
"Kieran is a disgusting human being doing this after I've just had a baby and still doing it till I caught them," she wrote. "No human being deserves this, especially being six months pregnant. Worst pain in the world."
Katie has since been silent on social media – except for posting a poem on 20 May which reflected her feelings.
It included the lines: "HATE has 4 letters, but so does LOVE / ENEMIES has 7 letters, but so does FRIENDS / LYING has 5 letters, but so does TRUTH / HURT has 4 letters, but so does HEAL."
Katie's thank you to fans came a few hours after husband Kieran broke his silence to send her two tweets, wishing her a happy birthday and pleading to fix her broken heart. It was the first time Kieran has spoken publicly since his affair was revealed.
"Happy birthday to my beautiful wife. I love you with all my heart forever and always," he wrote. "I will repair your heart and I am looking for the light at the end of the tunnel for our fairy tale ending. Believe in me xx."
Katie has not responded to Kieran.
