Alec Baldwin Watches from the Sidelines as Hilaria and 'DWTS' Pro Gleb Savchenko Turn Up the Heat

Alec Baldwin took a front-row seat as his wife, Hilaria, turned up the heat on "Dancing with the Stars," proving that family support can be just as captivating as the performance itself.

Alec Baldwin was all smiles as he attended the premiere of "Dancing with the Stars," cheering on his wife, Hilaria Baldwin. Before taking the stage for her first routine to Jennifer Lopez's "Let's Get Loud," Hilaria shared with her dance partner, Gleb Savchenko, that she had a history with dancing.

"I used to be a dancer. I had to stop because I broke my hip all the way through," she revealed. When Gleb asked how it happened, she explained, it was from "overuse."

In the lead-up to the premiere, Hilaria and Gleb moved their rehearsals to New York City. "With one week to go, I'm taking Gleb to New York, where I live," she said. "I'm so excited to share this experience with my family."

Alec joined them at rehearsal and praised his wife's dedication. "She's a hard worker," he told reporters. "This was her life until she got injured so she's just going to give it everything she has. I'm proud of her, very proud of her."

The fun continued when Alec asked to join in. Rather than dancing with Hilaria, he and Gleb showcased a few moves together on the floor.

When it was time for the actual performance, Hilaria and Gleb delivered a fiery Cha Cha. The pair shared some close moments toward the finale, and the camera briefly captured Alec clapping from the sidelines, though his expression remained serious.

The Baldwins' children were also in the audience, cheering their mother on as she lit up the dance floor.
