But as her fellow anchors and longtime viewers say their farewells to the broadcasting legend, her children want to remind everyone that's she's so much more than that.
Cody joined us in the studio to celebrate KLG's big day, but Cassidy couldn't make it since she's currently filming a series with mom's pal Roma Downey. But the duo were side-by-side in their pre-taped message, and they spoke of the many values they've learned from having a role model like their mom in their lives — from kindness to generosity to having a strong work ethic.
However, Cassidy considers a single quote from her mom to be "the biggest life lesson" she's ever learned. Kathie Lee told her, "If you have a pulse, you have a purpose."
Here at TODAY, we're familiar with those short and sweet bits of inspiration from KLG, like the self-empowering message that she often shares: "My joy is non-negotiable."
And according to Cody, some of that rich wisdom has been filtered down through the generations.
"The best advice I've ever gotten from mom actually came from her father, Pawpop, and he had told her at a very early age, 'Find something you love to do and then figure out a way to get paid for it.'"
Her career is a testament to that.
But not everything they've learned about their mom's life has been taught by her directly. Their father, the late NFL star and sports commentator Frank Gifford, gave them a one-of-a-kind insight into the woman who means so much to them.
"What I learned through my dad's eyes about my mom was just how proud he was of her," Cody recalled.
Frank and Kathie Lee had been married for 29 when he died in 2015.
"I just remember in the last couple years before our dad passed away, if I was ever home and we're sitting watching Mom at 10 a.m., he used to just always say — first he would say, 'Oh, boy, you're mom's so pretty!' — and then he used to always say, 'You know, there's no one else like her.' And he said, 'Who knows if there ever will be?'" Cassidy shared.
He boasted to his children about how she connected to people and how that was truly one of her strengths. And it still is.
"She's still kickin' butt doing what she's doing," Cassidy said, adding, "She has more energy than we have."
TODAY viewers has seen that for themselves, as has KLG's entire TODAY family — especially her fourth-hour co-anchor and cohort Hoda Kotb.
"When Hoda came into our lives, there's this little spark, this little flame inside of mom — we've all seen it — that radiates outwards," Cody explained.
"I think there are friends and then there are friends like Hoda," Cassidy said in agreement.
But as KLG says goodbye to working with Hoda and the rest of her on-air family, she has a lot to look forward, too.
"What's next for mom? I want her to rest," Cody said with a laugh. "I want her to just chill out for a little, but it's going to be movies, music, spending time with friends."
They closed their touching tribute with a message (and a fitting toast!) to their matriarch-and-more.
"We love you, Mama," Cassidy said. "And I just can't wait to see how God blesses you in this next step."
