Scotty made the admission while publicising his new book, Scotty T: A Shore Thing, adding that he dealt with the situation "properly and respectfully".
In an extract published exclusively in The Sun, Scotty recalls: "She said she felt it was only right to let me know she was pregnant and that she wasn't going to go through with it.
"Forgive me for saying it, but the sudden relief I experienced when she said that she wasn't planning on keeping the baby was overwhelming, 'cos I knew for sure that I wasn't ready to be a dad.
"I had enough trouble looking after myself, never mind a mini Scotty T. F***ing hell!"
Scotty, who claims to have slept with 1,000 women, insists that it was the only time one of his former conquests has fallen pregnant.
Meanwhile, Scotty has recently clarified his relationship status with Francesca Toole
Scotty was first romantically linked to Francesca after leaving the Celebrity Big Brother house earlier this year. However, despite things hotting up over the following months and him describing her as "the love of his life" in September, Scotty was soon writing in his Daily Star Online column that Francesca had dumped him.
"Got dumped by my girlfriend and had to change my number, buzzing," he said.
All appears to be back on track now, though. During a Facebook Live chat this week, Scotty confirmed that he is still dating Francesca, but described their romance as "casual".
"We are together, but it's a casual thing. When people start branding it a relationship, it causes sh*t," he said.
Scotty T: A Shore Thing, published by Simon and Schuster, is on sale from Thursday 20 October.
