The couple teased the media in July (14) when announcing plans to wed in MCCarthy's hometown of Chicago on 15 August, but reports suggest the nuptials took place in suburb St. Charles over the weekend - and groom Wahlberg's movie star brother was a no-show.
He may have missed the wedding, but Mark made an effort to congratulate his brother on his big day, tweeting, "Congratulations@DonnieWahlberg and @JennyMCCarthy, so happy for you both today."
The actor, his wife Rhea Durham and their kids also filmed an Instagram video congratulating the newlyweds and posted it online, revealing they were celebrating daughter Ella's 11th birthday in Los Angeles.
Meanwhile in St. Charles, MCCarthy's former The View co-star Sherri Shepherd was on hand for the ceremony at the Hotel Baker, as well as Wahlberg's New Kids on the Block bandmates Jordan Knight and Danny Wood, according to local newspaper The Courier-News.
The wedding is the second for both stars - Wahlberg has two sons from his nine-year marriage to Kim Fey, which ended in divorce in 2008, and MCCarthy shares a son, Evan, with her ex John Asher. They divorced in 2005.
