England goalkeeper Joe Hart married Kimberly Crew at a lavish Italian wedding ceremony over the weekend.
But, while most people were busy congratulating the duo, it seems as if one person wasn’t so happy to hear about their good news.
According to The Sun, Katie tweeted: "All Harts go out to the married couple is he going to tell her the truth about us xx."
The post was deleted hours later, but fans were able to screen grab and capture the message.
And, unsurprisingly, it sparked fury amongst football fans.
One wrote: “What a despicable human being she is.”
Another added: "So Katie Price reckons something happened between her and Joe Hart?”, adding a laughing emoticon face.
Speaking to The Sun, a source (claiming to be a friend of Joe’s) said: "It's hardly the perfect start to married life.
"Given the highs of the previous day, it's an unwelcome distraction. Unfortunately it appears Katie realised the impact this tweet could have on the newlyweds a few hours after writing it."
Katie’s tweet comes weeks after she threatened to expose a secret A-list lover.
She told the Daily Star: “There’s a couple of guys in there [my autobiography] who have upset me, so it’s about time I revealed the truth about them.
“They are household names.”
She continued: “I was seeing one of them for two or three months before Kieran.
“He’s a world-famous professional and it’s... oh my God, if people knew. He’s British.
“I’m not saying anything more, but any girl would be jealous as f***.”
Neither Joe Hart, Kimberly Crew, or Katie Price have commented on the mum-of-five’s alleged Twitter post.
