Louise Redknapp’s sons tower above her as she shares birthday tribute to Beau, 16

LOUISE Redknapp shared a sweet birthday tribute to her 16-year-old son Beau - but fans could not believe how grown up he looked.

The teenager could be seen towering over his pop star mum in a throwback holiday snap.

Louise, who shares sons Beau and Charlie, 20, with footballer ex Jamie Redknapp, posted the touching post on Sunday.

The Eternal singer shared a series of snaps of Beau over the years to mark his 16th birthday, including a picture of her holidaying with her boys.

Beau and Charlie posed next to their mum looking a few feet taller than their famous mum.

Louise captioned it: "To my little ray of sunshine, you’ll always be my baby no matter how old you get, I’m so incredibly proud of you, keep working hard and achieve all your dreams and goals I’ll always be by your side and supporting from the side lines.

"I love you more than anything happy birthday beautiful. Sweet sixteen Beau Beau."

Louise's fans were stunned by how tall her boys are.

One wrote: "Crikey Louise they are towering over you, one day I'll be in the same position lol! (Also with my beautiful girl) Hope he has a great day...gorgeous boys just like their mama."

A second posted: "Wow do kids that were once so small get so big. My two boys are the same. It just crazy but beautiful."

A third commented: "What's the Gary Barlow genetic connection?," in reference to the Take That star's eldest son Daniel, who is 6 feet 2 inches.

Just last week student Charley posted a sweet tribute on Instagram to celebrate his mum’s 50th birthday on Monday.

The heartwarming photo showed Charley and Louise smiling for the camera during a recent meal out.

While the pair were sat down, their visible height difference couldn't be ignored by fans.

With Louise standing just above five feet, Charley takes after his father, Jamie, who is six feet tall.

Taking to his Story, the celebrity offspring wrote in his caption: "Happy birthday mum. I love you."

In a recent video, taken at the five-star Hotel Cala Di Volpe in Porto Cervo, Charley was seen scooping his two-year-old brother Raphael into his arms.

The adorable footage saw the siblings enjoy a heartfelt moment on holiday.

Charley last year flew the nest and moved to Arizona to play rugby.

Former Strictly star Louise revealed her heartache at the time ahead of his move to university in America.

She told Metro: "I keep crying. I cry like 10 times a day at the moment, like if someone’s nice to me I start crying like, 'Sorry it’s just my son’s going to university'.

"Everyone who’s had kids go off to university say, it’s normal. I’m super proud of him but, God, I’m gonna miss him."

Louise and her ex Jamie met back in 1995 and tied the knot three years later.

The former couple split in 2017 after 19 years of marriage following Louise's stint on Strictly Come Dancing.

Their divorce was then official by 2018.

Jamie started dating model Frida Andersson-Lourie in 2020 and announced that she was pregnant with their first child in May 2021.
