Simon Cowell arranged for a dinosaur to entertain guests at his son Eric's birthday party on Sunday (19.02.17).
The 'X Factor' boss threw little Eric - his child with fiancée Lauren Silverman - a lavish bash in London to mark him turning three and guests were entertained by a life-life robotic reptile.
The dino fun was revealed by TV star Katie Piper who attended the party with her two-year-old daughter Belle - her child with her husband Richard Sutton.
Posting a photograph of her and Belle at the bash and Simon, 57, having fun with the dinosaur on her Instagram account, she wrote: "Surprise guest at Eric's birthday - First time Belle has seen a real dinosaur!!! (sic)"
Eric turned three on February 14 but the party was held at the Arts Club in London's Mayfair district a few days later at the weekend and the guest list was packed with stars.
Simon's fellow 'Britain's Got Talent' judges Amanda Holden, Alesha Dixon and David Walliams and his long-time friend and 'X Factor' veteran Louis Walsh were all in attendance at the celebration.
Simon and Lauren chose the private members' club as the venue for Eric's second birthday.
