Lara Spencer spent quality time with her oldest child, Duff, over the weekend and delighted fans with photos of their antics.
The Good Morning America host sparked a reaction from her social media followers with a new snapshot alongside the 22-year-old.
They couldn't get over how grown up and tall he was he towered over his 5ft 8 mom.
The image showed the pair inside billionaire, Marc Lasry's home and Lara captioned the post: "Marc Lasry you are the coolest. Thanks for sharing Milwaukee Bucks stories and giving us the tour. Such a fun day at your beautiful home. #2021NBACHAMPS."
Fans also noted Duff's startling resemblance to his dad, David Haffenreffer, who is a real estate broker and former journalist.
Lara shares Duff and his younger sister, Katharine, with her ex-husband and they've remained on good terms despite their divorce in 2015.
They'd been married for 15 years when they decided to end their marriage saying at the time that their children "remain our top priority," adding: "We will raise them and care for them together."
And they've kept their word. David often pops up on Lara's social media pages when their children are involved.
Last year they reunited when they dropped Katharine off at college in Nashville.
The mom-of-two is now married to entrepreneur and chief executive officer of MarketAxess Holdings, Richard McVey.
They met a year after her divorce on a blind date and tied the knot in Colorado in 2018.
When she walked down the aisle, Lara was accompanied by Duff.
Lara shared a video from the tender moment earlier this year when she celebrated Duff's 22nd birthday.
Taking to Instagram, the mom of two penned a tribute to her son on his big day, writing: "Happy GOLDEN Birthday Duff!!! Found this video today. My son filling in for my beloved Dad, walking me down the aisle."
Duff stepped in to walk his mom down the aisle as Lara's own father passed away in January 2011.
The TV host continued: "That was 5 plus years ago and what a moment for me. But 22 years ago today --1-22-02--now THAT was everything. The day I gave birth to this kid--and my life as a mom began. I love you my Duff. Wishing you a year filled with happiness, good health, great adventures, and a million laughs."
