Simon Cowell left fans speechless with how “grown-up” his son Eric looks when he shared a rare photo with him.
The music mogul, 65, shares his 11-year-old lookalike child with his fiancée Lauren Silverman, 48.
Cowell posted a snap with the pre-teen and his pet chihuahua, Daisy, backstage during filming of the quarter-finals of America’s Got Talent.
The X Factor judge wore his signature black T-shirt and sat in a chair in his dressing room, while Eric, donning a blue AGT T-shirt, smiled as he put an arm around his famous father.
In the Instagram carousel, Cowell also shared a video of the screaming live audience in the AGT studio and a snap of him talking to the camera backstage.
“Everyone’s happy,” the Syco founder captioned the post, shared on Thursday.
Fans flooded the comments with their shock over how “big” Eric has gotten.
“That couldn't be Eric. I feel soooooo old now,” one baffled follower wrote.
“Eric is the image of you. Wow he's so grown up. Lovely to see,” another added.
“Wow is that Eric? So grown up,” a third posted.
Someone else remarked: “Oh my goodness I remember when he was born. Can't believe how big he is, Handsome like his dad!”
Cowell is a judge on AGT alongside Howie Mandel, Mel B, and Sofia Vergara.

During Tuesday's second quarter-final, the live results revealed guitarist Bay Melnick Virgolino, Leo High School Choir and dance troupe Unreal will go through to the semi-final.
The artists will return to the stage on September 16 to compete in the top 12.
Cowell previously revealed “headstrong” Eric is an excellent judge on talent shows.
When asked on Loose Women if Eric ever gives him advice on his various shows, he replied: "Oh my God yes, non-stop by the way.
“I have a good idea what he’s going to be when older. He’s got his own opinion and he’s his own man which is really important."

He continued: "The great thing is when I watch the shows, when they go out I’m looking at Eric thinking does he like something? and he’s normally right.”
The music mogul, who previously vowed never to get married or have children, added that he was "late to the party" regarding fatherhood but described it as the "best thing" to have happened to him.
Cowell, Silverman, and Eric count the fashionable Cotswolds as their base, joining a throng of A-listers who flock there including the Beckhams, Jeremy Clarkson, Kate Moss, and Ellen DeGeneres.
They swapped London for a lavish £8 million farmhouse in Oxfordshire in 2021.
Cowell and Silverman - who got engaged in 2021 - moved to the exclusive country enclave following a series of break-ins at their former £45 million home in Holland Park, west London.
