John Cena and Nikki Bella

John Cena has broken his silence after splitting from fiancée Nikki Bella.

The WWE stars, who had been together six years, were due to marry on May 5,  a year after John got down on one knee during Wrestlemania 33.

But just weeks before their wedding they announced their shock separation.

Speaking from CinemaCon 2018 at The Colosseum at Caesars Palace in Las Vegas, he admitted: “It sucks."

He added to Entertainment Tonight: “There’s no other way to say it. I love Nicole with all my heart, and that’s that."

Nikki is yet to address their split since she released the statement, but over the weekend she put on a brave face for her first public appearance.

At the event, Brie praised her sister's strength and revealed their marriage break down would be shown on their E! Show Total Bellas.

She said: “She’s good, they call her fearless Nikki for a reason. She always puts on that brave face. My sister has more strength than any other woman I know, especially Wonder Woman. She’s bigger than that."

Mum-of-one Brie added to People: “I really had to take a step back and allow it and that was really hard on me because it’s my twin. I want to protect her from everything. This has been the hardest season to film for me because all I want to do is protect her and keep everyone away, but this is what we do.”

Meanwhile, Brie was forced to shoot down reports suggesting she was furious with John over the split and how her sister had been treated.

She wrote in an Instagram story recently: "I'd never say this and I'll always love @JohnCena like a brother. He'll always be family. My heart is hurting for him and my sister #truth."
