Presenter Jenny McCarthy and actor Donnie Wahlberg married at the Hotel Baker in St Charles, Illinois on Sunday.
People.com reports that Wahlberg's New Kids on the Block bandmates, Jordan Knight, Danny Wood and Jonathan Knight, were among the guests.
Wahlberg's brother Mark was unable to attend but tweeted his best wishes and sent a congratulatory video with his family in which he said: "I love you, Donnie, we're very happy for you. Sorry we couldn't be there, we'll see you soon."
This is the second marriage for both McCarthy and Wahlberg, who began dating last summer and became engaged in April.
