Heavyweight star Alistair Overeem has finally made it to the UFC, and it’s fair to say he’s as happy as the rest of us about it.

“Honestly, it feels like one of the biggest days in my life, a sort of life-changing thing,” Overeem told MMAfighting after news of his signing emerged earlier today. “UFC is really big, they just did the FOX deal, you have all these possible match-ups happening right now, so for me, it’s a very exciting time, the team is very excited, UFC people are very excited.”

Overeem’s first fight will be a blockbuster against Brock Lesnar on December 30th, and according to the former Strikeforce heavyweight champion he turned down a title shot in order to face the former holder of the belt.

“I got offered to fight for the championship belt but that would mean I had to wait, because of course dos Santos is fighting Velasquez Nov. 12, it’s going to be a great fight, then probably these guys are going to need some healing time, relaxing time, so November plus six months, that will probably be May. I’m a fighter, I like to be active, so then some names came rolling out and Brock Lesnar was among them and I think it’s a dream match-up. The fans wants to see it; I want to see it. I’m very excited about this fight, so I immediately said yes.”
