'Moves like his mum!': David Beckham celebrates son Romeo turning 20 with a cute throwback clip as he dances up a storm watching mother Victoria perform on stage with the Spice Girls

Romeo Beckham turned 20 years old on Thursday and was flooded with well-wishes from his family to mark the occasion. 

And father David, 47, took to his Instagram to share a fun throwback clip of the birthday boy dancing as he watched his mother Victoria, now 48, on stage at a Spice Girls concert.

In the video a toddler aged Romeo dons a suit as he sings along - knowing every word - to the girl band's performance of Stop.

The tot can be seen gazing up at his mother, who last performed with the band in 2008, stage as he sings into an imaginary microphone and boogies along.  

Posh Spice Victoria dressed in a figure hugging gold ensemble alongside Geri Horner and Mel Chisholm, then lovingly waved when she noticed her son. 

David who also shares Brooklyn, 23, Cruz, 17, and daughter Harper, 11, with his wife, captioned the clip: 'Always the little performer with the moves following his mum ( POSH SPICE ) BIRTHDAY BOY we love you x'.

The England legend also shared a video of his son's first attempts at shaving as he gushed 'we are so proud of you'. 

David lovingly guided his son as he lathered his face with shaving foam and trimmed his facial hair for the first time. 

Victoria also shared a slew of snaps to her social media on Thursday to mark the mile stone.  

One showed the proud parents looking youthful as they posed during a meal, with Victoria sporting long blonde hair and a dark tan. 

The image above showed Romeo with David as he pulled a grumpy pout while sitting on his lap.

She penned in her post: 'Happy Birthday @romeobeckham! You have the kindest heart and the sweetest soul. We love you and are so so proud of the incredible young man you have become. 

'You light up a room the moment you walk in, you're hardworking and talented, we couldn't be prouder of you Romeo. Happy Birthday! @davidbeckham.'

Other throwback shots showed Romeo when he was younger on holidays, in his football kit and sailing as he donned a life jacket. 

Victoria also shared a more recent photo with her son as they beamed for a snap together.

It comes after last month Romeo looked in good spirits as he took to the pitch for football team Inter Miami at DRV PNK Stadium. 

The aspiring footballer, whose father David owns the club, led his team to victory against New England Revolution II, with the final score 4-2.

David was there to show his support for his sporty son and his team, wearing a pink Inter Miami baseball cap.

Victoria also threw her support behind Romeo, taking to her Instagram Story to share a snap of him with his father in the stadium.

She captioned it: 'I love you so much!! (you too @davidbeckham). Proud of you tonight @romeobeckham'.

She also shared a photo of David posing for a picture with some fans, writing: 'Amazing @intermiamicf fans showing up to support!! Great game tonight @romeobeckham'.

Romeo sported his light pink Beckham 37 jersey along with a matching pair of shorts and shared a shot of him with the ball to his own Instagram Story.

He wrote along the top: 'Great win' followed by a white heart emoji. 

Romeo scored one assist during the game, his ninth one this campaign, meaning he continues to lead the team in assists.  

The second oldest of Beckham's four children was playing after his shock split with Storm Models client Mia Regan after three years together.
