The triple-threat star also revealed what she really thinks of their couple name, J-Rod.
Jennifer Lopez insists that Alex Rodriguez is a good dancer, but Today show co-host Hoda Kotb isn't convinced.
The triple-threat star showed up on the morning show to promote her #WorldOfDanceChallenge, which led Kotb and Sannah Guthrie to ask if her new boyfriend can bust a move. "He…He…is. He’s a good dancer. We have a good time," she said hesitantly, laughing. "Again, one of the things I love is that he loves to dance and I love to dance.”

When Kotb joked that Lopez, 47, kind of implied that Rodriguez, 41, is not great on the dance floor, she quipped, "No, I never said that! He can dance. He can merengue."
"He does all the important stuff for me," Lopez added. "When the Spanish music comes on, he knows what he is doing."
Lopez also revealed what she really thinks of their couple name, J-Rod. "I don't care. It doesn't matter," she said. "I figured something like that would happen."
However, when asked what she thought of their alternate couple name, A-Lo, she admitted, "I don't like that so much."
The power couple made their first red carpet appearance at the Met Gala last week, and inside the event, Lopez was seen dancing to Migos' “Bad and Boujee” song, while the former MLB player sat on the sidelines.
While Rodriguez wasn't feeling the music at the Met ball, he did heat up the dance floor, when he and Lopez were in the Dominican Republic last month.
A source close to the "Booty" singer recently told ET that Lopez and Rodriguez"are madly in love."
"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 of their Met Gala appearance. "Wherever Jennifer went, Alex followed. They only had eyes for each other."
