WWE STAR Brock Lesnar suffered an awkward wardrobe malfunction when he faced R-Truth on SmackDown

The wrestling icons faced off in the lead-up to Lesnar’s bout with John Cena at Wrestlepalooza on Saturday.

His pants ripped open during an F-5 on R-Truth

The pair exchanged words before R-Truth remonstrated Lesnar for delivering an F-5 to Cena.

Lesnar replied by hitting the same move on Truth, but in the explosive movement, he managed to tear through his jeans.

The 48-year-old seemed stunned at first, before pointing to the large rip with a large grin.

He slapped the back of his thighs and roared with laughter as he broke from his stoic character in the ring.

He even donned a cowboy hat and gave the crowd a wiggle as his bright blue underwear showed through the tear.

He broke character further as he walked away from the ring, telling the cameraman: “F*** it Stu. I ripped my pants.”

Fans adored the unscripted moment, bringing even more comedy to an already light-hearted segment, and giving a glimpse into the man behind the facade of Brock Lesnar.

One fan on X said: “Never saw this guys smiling like this.”

Another added: “Brock breaking character this time has made me a fan for the first time ever.”

A third fan said: “He seemed embarrassed, but humble, having fun. I felt we saw the real Brock Lesnar here.”

And a fourth commented on the bizarre sight of his silly outburst, saying: “Brock doing a booty shake? Now I’ve seen everything.”

Lesnar faced down WWE legend Cena a week later at Wrestlepalooza.

The South Dakota native stunned the world in that match when he beat Cena comfortably.

It was the latest entry in a comeback rivalry for the WWE star.

Lesnar had been absent from the promotion for two years before making his return.

He immediately ignited a rivalry with Cena when he ambushed him following his loss to Cody Rhodes.
