RADIO presenter Lottie Ryan doesn't think Ronan Keating will like being referred to as "Grandad" at the age of 46.

The Boyzone frontman's son Jack made the surprise birth announcement on his Instagram account on Tuesday.

Ronan posted a heart emoji and commented: "Little cutie." The former Love Island contestant, who had a baby girl, confusingly claimed to be single recently and confessed to using a dating app.
