Pitt posed for a selfie with Boyzone's Keith Duffy

The weather gods played ball yesterday for Bruce Springsteen's highly-anticipated gig in Dublin, with the sun shining all afternoon and into the early evening.

And there were more than a few famous faces amongst the tens of thousands of fans who filed into Croke Park to see The Boss, too.

Brad Pitt was spotted - presumably in the post seats/corporate boxes - as former Boyzone member Keith Duffy posted a selfie with the Hollywood superstar.

Nick Jonas of The Jonas Brothers has been spotted out and out in Dublin lately, too - bringing his young daughter to Peppa Pig Live show at the 3Olympia Theatre last weekend, and sticking around to see Springsteen at Ireland's biggest stadium.

Jonas is currently filming John Carney's new film 'Power Ballad' in Dublin with Paul Rudd. Rudd was indeed, spotted filming in Dublin earlier in the week, and was reportedly seen at the Croke Park gig, too.

Other big names also spotted in the crowd were actors Benicio Del Toro, as well as 'Wednesday' actor Luis Guzman. Season 2 of 'Wednesday' is currently filming in Ireland.
