Now this is a proposal!
Organised by RTE 2's The Fear, this poor man had no idea what his boyfriend had planned for him.
They're just sitting down having a chat at Electric Picnic when his partner gets down on one knee. And then the flash mob arrives.
Led by comedian Fred Cooke (who you might remember from those Spar ads!), the gatecrashers sing, dance and implore Babbins to say yes.
And he does. Yay!
And over on Twitter, Panti herself has offered her congrats.
