"Oh my God Colin," she says while embracing the man. "This is my doctor that gave birth to my baby, I haven't seen you for years."
The pop star then visibly began welling up in tears.
While the band continued playing the song, Adele was too overcome to immediately resume vocals. Instead, she sweetly asked of the audience, "Will you sing it for me? That man delivered my baby."
The fans in attendance, of course, obliged.
She then, according to Daily Mail, told the audience: "I took a double look and he's here. I'm desperate for another baby, Colin, bloody hell, so I might give you a call. My son turned 11 a couple of weeks ago and he's not a baby anymore, it's crazy."
"I don't want everyone to know who has seen inside my insides. My womb is starting to ache a little bit."
"It's like, 'Baby, baby, baby. Need a baby, need a baby'," she joked.
Adele, and then-husband Simon Konecki, welcomed son Angelo in October 2012.
