Nicole Kidman and Keith Urban Pose with Teenage Daughters Sunday and Faith at Her AFI Tribute

Nicole Kidman and Keith Urban glammed up for their night out in honor of the actress — and were joined by their teenage daughters on the red carpet for the first time!

It was the Bombshell star's time to shine as she was honored at the 49th AFI Life Achievement Award Gala held at the Dolby Theatre in Hollywood, California on Saturday, April 27.

Posing together on the red carpet, Kidman, 56, wore a custom version of a Balenciaga Fall 24 fitted gown that was embroidered in gold sequins, while her husband sported a black suit with black silk lapels, a white shirt, black tie and black boots.

Sunday Rose, 15, and Faith Margaret, 13, were among family members in attendance with Sunday wearing a floral strapless gown and Faith in a striking coral dress. The actress's niece, Sybella Hawley — who is Kidman's sister Antonia's daughter — also posed with the family of four, wearing a red gown featuring a corset top and draped silk skirt.

During her acceptance speech, the actress praised Urban, 56, her two daughters and her family as a whole, noting that there was an "enormous amount of luck in my life," but adding that, "there's also the most important thing, love."

"Big, big love. And then right there is the love of my life, and the loves of my life. My daughters have never been anywhere publicly with me on a red carpet, tonight was their first night, so they're here, Sunday and Faith."

Kidman noted that her mom wasn't at the event, adding "but they said there's a live stream available for her and she's watching it, so I hope, and that's what I love about technology. And my papa who isn't here, but I feel him every day."

"And then there's all my nieces and nephews and my sissy and my beautiful aunt and her husband, who's our family now. And I am really, this is all because of you, and I love you so much. So there's no place like home, as they say. You're my home. And thank you for flying halfway across the world," she continued.

Kidman also spoke exclusively with PEOPLE at the gala about what it was like to have Sunday and Faith witness such special moments in her career. 

"You'll have to ask them," she jokingly told PEOPLE. 

"I think they're just like ... they want to get started on their own careers," the actress continued of her daughters, adding,"They are here to support me, and they're very, very supportive and incredibly loving."

Kidman also explained that, while Sunday and Faith had attended the gala to support her, they were especially looking forward to one part of the night.

"We're going to do a post wrap-up at the house late, late tonight," the actress revealed, adding, "There's a party afterwards, and they're like, 'Oh, there's a party?' "

"That's what they're excited about," she teased.

For the event itself, Kidman was surrounded by friends and coworkers who paid tribute to her as she received the honor. Guests included her costars in Big Little Lies, Reese Witherspoon and Meryl Streep, her close friend Naomi Watts and Morgan Freeman, who worked with Kidman on the Paramount series Lioness.

The AFI Life Achievement Award has been presented by the American Film Institute since 1973 to an "individual whose career in motion pictures has greatly contributed to the enrichment of American Culture," the organization's website said.

Kidman recently reflected on her career by sharing a video to Instagram of herself at 14 in her first role — Helen in Bush Christmas in 1983. She reflected on receiving the AFI's honor in the caption.
