Sylvester Stallone’s 70th birthday celebration was a knockout to say the least. The Rocky star celebrated his special day on July 6 in Monaco joined by his family and a royal guest of honor.

Monaco’s Prince Albert made an appearance on Wednesday night at the actor’s party held at Monte-Carlo’s La Trattoria restaurant. Sylvester shared a photo on Instagram of himself and Princess Charlene's husband shaking hands, looking like old buds.

The birthday boy told reporters, "I'm here at my friend Victoria's invitation. It's a surprise for me. I didn't expect such an evening. I thought for my 70th birthday, she would have offered me a hamburger and fries."

As far as his surprise guest goes, Sylvester admitted to the newspaper, “It made me really happy to see these people especially Prince Albert."
