Pink had a special delivery for her opening concert at Boston's Fenway Park.

A devoted fan went into early labor just before the Summer Carnival Tour concert on July 31, walked to the closest hospital to give birth and named her baby after the "Raise Your Glass" singer's family, according to a release from Boston Brigham and Women's Hospital.

Angela Mercer was 31 weeks pregnant, far from her due date when she traveled from her home in Albany, New York, to the Boston concert, according to the release posted on the hospital's Facebook page announcing the news. The outing was a girls' trip with Mercer's sister-in-law Amy and mother Barbara.

"However, things didn’t quite go to plan," the hospital post reads. Mercer started having contractions shortly after arriving for the show and called her doctor, who advised her to get to a hospital.

With all the traffic surrounding Fenway for the concert, Mercer couldn't find a ride to the nearest hospital. So the girls' trip became a walking trek in concert apparel of about a mile to Brigham and Women’s Hospital, where Mercer gave birth to a healthy baby boy.

Pink, who has been married to Carey Hart for 17 years, has a new fan named after her family – Aycen Hart.

"Baby Aycen was born right on his grandma Barbara’s birthday," according to the hospital post. "While the family didn’t get to enjoy the concert, they say they received the greatest gift of all – a healthy baby boy."

Mercer shared her thanks to the hospital staff in the post saying she and husband Ace were "so incredibly thankful."

Nurse Moira Crowley tells USA TODAY through a hospital statement that the concert-to-hospital delivery "will most certainly be one of the most memorable births throughout my career."

"The entire family not only left us with one of the best birth stories but also endless pink sparkles throughout our hallways," Crowley added. "We are all still thinking of them on Labor & Delivery and wish everyone a speedy recovery."

USA TODAY has reached out to Pink's media representative for comment.

Pink has gone through the life spectrum on her world tour. During a concert in Hyde Park, London, a fan threw a bag seemingly containing their mother's ashes on stage. In the viral video that followed Pink paused the concert to take in the moment.

"This is your mom?" Pink can be heard asking in a video as she picked up the bag. "I don't know how I feel about this."
