The aspiring actress was spotted hanging out with the glitterati in Lillie's Bordello over the weekend.
The Limerick model, who was linked last year with Calum Best, was enjoying a night on the tiles as she bucked the trend of staying in during January with a foray into the celeb club.
She has just began a college course in personal training and has decided to put her modelling career on the back burner.
She has been keeping a low profile of late after hitting the headlines last October. She was subjected to a violent attack while in McDonald's after a female customer hit her in the face after Madeline reprimanded her for being rude to a staff member.
Just two months later, she took to her Twitter to claim she was victim of an altercation in Limerick city. She said: "That's Limerick city when you reject a boy and then he punches you in the face. Can't wait to get back to Dublin. I'm okay, I hit him harder than he hit me."
Madeleine wasn't the only familiar face in the club, though. Also spotted in the Grafton Street haunt was fashion designer Dawn Fitzgerald, as well as members of the Irish band The Thrills and actor Liam Cunningham.
