Popstar Jesse McCartney marries actress Katie Peterson in stunning outdoor ceremony - with their dog as 'flower girl'

Popstar Jesse McCartney has married girlfriend Katie Peterson in a romantic ceremony in Carmel, California.

The 'Beautiful Soul' singer married the actress on the grounds of the rustic Santa Lucia Preserve, where they were married by Peterson's uncle in front of 147 guests including their beloved dog Bailey, who served as a flower girl.

"I think that moment of settling in at the altar and just watching her come down is going to be pretty special and having our families there and witnessing all of it," the singer told People magazine ahead of the nuptials. 

"I cry watching a Subaru commercial. That kind of sums it up for you," the 34-year-old added. "So I don't know how I'm going to get through this."

But the outdoor ceremony went off without a hitch as the bride walked down the aisle to a string quartet's version of Eric Clapton's 'Wonderful Tonight', after the wedding park walked down the aisle to a string version of the Jurassic Park theme song.

The newlyweds later shared their first dance to 'Lover' by Taylor Swift.

The couple were engaged in 2019, seven years after meeting at a bar Peterson was working in at the time, while McCartney was there celebrating a friend's birthday.

"I was sort of trying to sweet-talk her," the singer recalled to People. "I found her incredibly attractive and was just trying to charm her, but she wasn't having it. I eventually left my number on a napkin and she said, 'You didn't write your name down on it!' And I was like, 'Oh, of course, she probably got a million of these tonight.' I had to write my name down on the napkin and then eventually the rest is history!"
