Kate Hudson got to spend more quality time with Matthew McConaughey this weekend, reuniting with her former co-star at the fifth annual Baby2Baby Gala presented by John Paul Mitchell Systems in Culver City, California on Saturday night, just a few days after handing him and his Gold castmates the ensemble trophy at the Hollywood Film Awards last week. 

The hot rom-com couple, who starred together in classics of the genre like How To Lose A Guy in 10 Days and Fool's Gold, were radiant at the fundraising gala, where McConaughey was on hand to present the charity's Giving Tree Award to Jennifer Garner.

Earlier in the night, Hudson shared a cute video of the pre-party festivities to Instagram.

ET's Cameron Mathieson caught up with the 37-year-old actress on the red carpet at the gala, where she dished about her reasons for turning out to support Baby2Baby, which provides necessities to children in low-income families.

"I think it's always important to be involved with something that's a part of your community -- actually inside where you live and where your kids go to school," the Deepwater Horizon star said.

"I think that one of the things that really clicks with me is a lot of children don't even go to school because they don't even have shoes," Hudson added. "So hopefully every community has an organization that can provide those things for kids. And [Baby2Baby does] an amazing job."

ET also asked the mom of two about the story behind that great video of her singing at a birthday party for music mogul David Foster. Foster's daughter Sara posted a clip from the party, revealing Hudson's amazing singing voice as she was accompanied by John Mayer and Seal! 

When the video went viral, Hudson said she couldn’t believe it.

"I was like, 'What are you talking about?' I don't pay attention to anything," she admitted. "I've been so immersed in things that are important."

But Hudson was coy about the prospect of releasing an actual album in the future. "Not that I could say, but I'm always writing," she said.
