Adele performed twice at 3 Arena over the weekend, and - it's safe to say - everyone copped when Colin Farrell walked in with a new lady friend...

Since then, pictures have been circulating on social media of Colin with "the slim brunette"...

As for who she is, well, that remains a mystery. The Independent had this nugget of information: "The True Detective star has been enjoying himself this week and has been spotted in a number of top restaurants around the city. Colin, who is based in LA, was first spotted out with the mystery woman last month."

Other Irish celebs knocking around at Adele's gig included Edge and Hozier.Â
