Brian, who's a huge fan of the iconic singer, was left speechless after the Boss paid tribute on stage to his numerous sporting achievements.
The rocker told 40,000 fans at the RDS on Sunday that it was worth coming to Dublin alone just to meet Irish rugby captain and Leinster hero Brian O'Driscoll.
The Clontarf native attended the three-hour gig alongside his fiancee Amy Huberman and according to onlookers he was almost moved to tears by the touching sentiments offered by the superstar.
Despite the driving rain on the night, the loved-up couple let their hair down alongside hundreds of fellow revellers and were spotted really getting into the spirit of things.
Bruce was keen to show his love for the Irish, listing some of his favourite things about Dublin, including Burdock's fish 'n' chips and sipping Guinness in O'Donoghue's.
Earlier, Brian and Amy had partied at the Oxegen festival where they joined the thousands of fans who rocked out to some of the top music acts in the world and proved they're not your average celebrity couple by booking a Winnebago.
The couple left late on Saturday night in order to make the Springsteen concert on Sunday, with Brian said to have been miffed that he had been refused access to enter the stage-side viewing area during the Kings of Leon set. The rugby star is a big fan of the band and bagged two front-row tickets for their sell-out gig at the O2 last December.
The busy couple will jet off on a romantic break to the USA in the coming weeks, and are aiming to travel around the West Coast, marking Amy's first ever visit to Hollywood.
The Clinic actress is still celebrating following the launch of her debut novel, Hello Heartbreak, at the Sycamore club last week where she was joined by family, friends, fellow actresses Victoria Smurfit and Leigh Arnold and of course hubby-to-be Brian to celebrate.
Fresh from his Lions tour to South Africa, the smitten sportsman described her book as a "great read" and said he was very proud of her.
