A group of well-known Irish faces have given some hilarious dating advice for First Dates Ireland Extras, exclusively on the RTÉ Player.

Social media star James Kavanagh had a very useful tip for first dates that don't go quite as planned.

"Have a friend ready to get you out of the date if it's going bad", he said.

Crystal Swing singer Dervla Burke also provided some straightforward advice for guys hoping to make a good first impression.

She said: "Go for a shower, put on a bit of hair gel, put on a nice shirt and a nice smile of his face because nine times out of ten a girl will go to extreme lengths for a first date".

Can't Stop Dancing presenter Bláthnaid Treacy had her own take on approaching first dates, saying: "Be nice and casual about it and don't wear too much makeup."

Stephen Byrne added: "Just do you."

In another Extras clip about how to give off the right signals, Stephen and Bláithnaid tried out their best flirty look on-camera.

Amanda Brunker also shared what irritated her about first date behaviour, saying women play with their hair too much. "Stop being so obvious!", she joked.
