Robbie Williams joked that his wife Ayda Field is the oldest person he has ever slept with as she celebrated her 37th birthday.
The singer baked a cake for his wife of six years, and wrote his playful Happy Birthday message in icing on the top.
However, it seems Ayda saw the funny side, as she was all smiles as she leaned in to blow out her candles.
And it seems Ayda's birthday treat doesn't end there, as Robbie also shared a snap of her looking unimpressed and pointing at a TV screen airing some football.
Robbie and Ayda have two children together - three-and-a-half-year-old daughter Theodora Rose and son Charlton, who is 19 months.
