"You have been spending time with someone in particular... who? I haven't got it down here. What's his name again?" Corden quipped. "A-Rod? That's his name, right? Alex Rodriguez?"
"YES!" Lopez, 47, exclaimed. "He's the best. You would love him. Honestly, he's a great guy. He's fun, he's awesome."
Corden was quite inquisitive as to how the pair ended up on their first date. "Is there a secret room for really famous, really hot and attractive, successful people where they just go on dates that I don't know about?" he jokingly asked.
"I actually just tapped him on the shoulder and said, 'Hi,'" Lopez recalled.
Not letting up, Corden inquired, "Should I go on a date with A-Rod, where would he take me?"
"It's just normal. We just went to dinner," Lopez said, laughing.
"Everyone who saw them on Monday night could see how super into each other they are. They didn't leave each other's side for a minute," the source noted. "Wherever Jennifer went, Alex followed. They only had eyes for each other."
