Jenny, 41 and Donnie's representative confirmed that the couple had a quiet ceremony which lasted only 20 minutes and was attended by close family and friends at Hotel Baker in St Charles, Illinois, reported Us magazine.
One of the guests, Sherri Shepherd, shared a picture of her taking a morning flight to go to the couple's wedding, captioning it with, "Catching an early morning flight to Jenny McCarthy & Donnie Wahlberg's wedding. What a beautiful day to join as one before God! Congrats to two beautiful people!"
Other guests included New Kids on the Block's members Jordan Knight, Danny Wood and Jonathan Knight.
Donnie's brother, Hollywood star Mark Wahlberg, could not attend the wedding and apologised to the couple in a short video posted on Instagram.
"Congratulations guys! Congratulations from all of us! We wish we could be there - it's Ella's birthday today, she's 11," Mark said in the video, "I love you Donnie. I'm very happy for you. Sorry I couldn't be there, I'll see you soon."
This is the second marriage for Jenny and Donnie. Jenny was previously married to director John Mallory Asher before dating Jim Carrey in late 2000s.
Meanwhile, Donnie, 45, was previously married to recording engineer, Kim Fey.
