"It's been such a crazy year for her, so amazing, so many blessings," began Rodriguez, 45. "But to think in a span of 12 months, she's done the Super Bowl, New Year's [Eve] and now the inaugural, it's unbelievable."
"And what's interesting is she's most nervous about Washington, D.C. because of the responsibility," he continued, noting that J.Lo "wants more than anything -- like all of us -- to bring people together, to inspire."
"And you know, music and sports does that better than anything," added A-Rod.
Rodriguez also told Fallon that he's "gonna be surprised," adding, "She has something really cool. You're gonna love it."
