Alex Rodriquez might be considered one of the best major league baseball players of all time, but admitted now that he's dating Jennifer Lopez, none of that matters.

The former Yankee slugger joined Jimmy Fallon on "The Tonight Show" Thursday night to talk about his budding relationship with J.Lo, who he says is far more popular than he will ever be.

"This is like one of the most humbling experiences of my life," Rodriguez said. "When I was with the Yankees, and we won the world championship, and you wear the pinstripes, you think you're pretty cool, but then, you hang out with Jennifer, and they confuse me with the security guard all the time."

The 41-year-old athlete recounted the chaos of attending the Met Gala at J.Lo's side -- which was apparently too close for the red carpet photographers' liking.

"We were at the Met Ball, and the paparazzi were screaming at me, not even in English, 'Get the Hell out of the way, get out of the way! We're trying to take a picture,'" Rodriguez said.

Rodriguez was on Fallon to promote his latest role as a member of the "Shark Tank" panel for its upcoming season. The athlete is CEO of Arod Corp, with business ventures including real estate, auto dealerships, and high-end fitness centers in both Mexico and the U.S.

"You know what I love about 'Shark Tank?' For the next generation, you don't have to feel like you have to dunk a basketball or hit a home run to be really cool, you can actually wear a suit and tie, get an education, and also be cool," he said. "You can get the same high from getting a great deal, or inventing something as you can hitting a home run or winning a world championship."
