Tom Arnold blows the lid off Hugh Grant's criminal act against Madonna

Tom Arnold recently got candid and opened up about a shocking prank he and Hugh Grant played on Madonna.

The 66-year-old American actor and comedian stepped onto the What's Wrong with Orny Adams podcast, where he revealed he pulled off a brazen heist against Madonna by stealing from her personal belongings from her suite while she invited the duo to her private show in San Francisco.

Arnold shared, "Hugh Grant and I were best friends, so he had just done (the film) Four Weddings And a Funeral and I had done True Lies, so we had something going... (we) went out every night (for) five months in San Francisco.”

The Gardens of the Night actor and The Gentlemen star were backstage, as Madonna clearly had great “chemistry” with Grant and ended up inviting both of them to her suite.

Arnold recalled, "We get in the elevator and I go, 'Hugh, I swear to God my feelings will not be hurt if I get out of this elevator right now and go back to our hotel by myself. He's like, 'Tom, do you or do you not want to see me f***** Madonna?"

Calling to mind, he further added, "He's like, 'Stick around, mate, in about 10 minutes I'll be f***** Madonna.’”

Notably, the situation started to mess up as soon as they reached the suite and found themselves at ease when the 66-year-old American singer-songwriter and record producer was freshening up.

"So we're like making ourselves at home, and Hugh Grant grabs a bottle of $200 champagne and chugs it, and I see a giant white sheet cake there. So, I cut the corner piece with the most frosting..." Arnold shared.

The Hit and Run star went on to reminisce about finding the Grammy-winning singer’s Louis Vuitton luggage in the room, which gave them the idea of stealing from it.

Arnold said he asked Grant, "Are you thinking what I'm thinking?" and he replied, "Yes, let's steal some s*****."

Grant went on to steal "antique silverware..." Madonna came back in the room and yelled, "What are you f***** doing? That's my brother's birthday cake; we're going to surprise him with that tonight."

The Like a Virgin songstress uttered, "Get the f**** out of here. You guys are idiots," to which Arnold exclaimed, "You can still have s***** with Hugh Grant."
