MMA star Conor McGregor and his longterm love Dee Devlin have announced they will soon welcome a second child.

Dee Devlin, who was McGregor's partner long before international stardom came knocking, is expecting.

The Dubliner took to Instagram to share the news as she wished McGregor a happy birthday.

  "Happy 30th birthday babe! Thank you for being you! Love you to bits from me, Conor jr and the bump," Devlin wrote.

Also 30, she gave birth to the couple's son Conor Jr in May 2017.

Devlin and McGregor have been together for 11 years. 

McGregor previously said in 2013 that he was determined to make it as an athlete in order to provide for Dee and their future family.

"I’m doing this to secure my family’s future and Dee’s future. One day, I want myself and Dee to be able to chill on a beach and not have any worry in the world.

"That’s why I’m doing this. I want to be financially secure by the time I have kids. When that happens, I want to be ready."

He also stated in 2015, "My girlfriend has been there since the start. She has helped me throughout this career. If it wasn't for her, I probably wouldn't be where I am today."
