They are one of Ireland's best-known couples and poke fun at each other from time to time on social media, so when it comes to Brian O'Driscoll and Amy Huberman, nothing surprises us.

Since becoming a mother, Huberman, who has two children with the former rugby star, has kept her Twitter followers entertained by posting about the trials and tribulations of being a parent, and now she has directed her wit at her husband of five years.

Taking to Twitter, the 36-year-old actress-turned-author posted a sweet photo of her husband along with the caption: "Still holding on to his muscle form in his hands post rugby but the rest of him is fading away."

The couple welcomed baby Billy last November and already have a two-year old daughter, Sadie.
