Enrique Iglesias jokingly called his twins “tough to entertain” as he shared a rare video of his eight-month-old children.
The singer and his tennis player partner Anna Kournikova welcomed Nicholas and Lucy in December last year.
On his Instagram page, the Spanish star, 43, shared a video with his 13 million followers showing him running backwards and forwards while the giggling babies turned their heads to watch.
The clip was captioned: “Tough audience to entertain.”
In July, Kournikova, 37, posted a picture of the twins wearing World Cup t-shirts.
The Russian former athlete shared a snap of the babies each wearing a football shirt of their parents’ countries as Russia took on Spain in the football tournament.
The adorable image showed Kournikova with a baby in each arm, with Nicholas in a blue top and Lucy in white.
