Turning the event into a family affair, the Hollywood couple brought along their two daughters James, 2, and their second infant daughter who was born in September. The pair have yet to announce the child's name publicly.
"This is one of the rare occasions when we thought we got to bring the whole clan," Reynolds explained to Extra about bringing along his daughters. "I'd regret it in 20 years if I didn't."
Notably, James who was seen sporting a varsity jacket and curly blonde hair, stole the microphone at one point while the family posed for photos.
"It's not the first time she's snatched a mic out of someone's hands. When she's 20, she can happily do whatever she wants. Thirty — I'm gonna up that to 30," Reynolds joked.
The Deadpool star also expressed his love for Lively stating, "I want to thank my wife, Blake, who is sitting right there, who is everything to me. You are the best thing that has ever happened to me."
"You make everything better. You make everything in my life better. You've given me two of the most incredible children I've ever hoped to have," he continued.
