Kate Hudson became a blushing girlfriend as she was quizzed about her romance with baseball star Alex Rodriguez on U.S. TV on Wednesday.

The actress was making an appearance on Oprah to promote upcoming movie musical Nine when the chat turned to her love life - and Hudson turned into a giggling wreck.

The star chuckled, "Oh, you're gonna do it to me," and then buried her head in her hands as host Oprah Winfrey flashed a photo of Hudson and her beau kissing, and asked, "So, how did y'all meet?"

The giddy actress responded by saying, "No comment," but Winfrey wouldn't change the topic, asking, "You can't tell me how you met?"

Hudson stumbled over her words, stating, "I don't even know where to begin," prompting Oprah to offer, "At a grocery store, at a party...?"

The actress finally gave up, "(It was) years ago... like, randomly."

And when the host asked, "And things are going well?" Hudson replied, "I am very happy."
