The couple, who got engaged in April, are set to tie the knot on Saturday (30.08.14) in a glamorous ceremony in New York in front of their close friends and family.
A source told the HollywoodLife.com: ''They are getting married this weekend and their friends and Donnie's family are flying to New York for the ceremony.''
The 41-year-old beauty - who was recently axed from 'The View' - hinted that her nuptials were soon approaching in July when she admitted that she was in a rush to find the perfect gown for her big day.
The former Playboy model and her fiancé have also been struggling to cut down their guest list, but they refused to get stressed over the upcoming nuptials.
She said last month: ''The hardest part is we have to cut down the wedding list, because the place we're getting married at, it's very boutique. With Donnie's 800 relatives - yes, 800. I've got 6,000 McCarthys. It's going to be hard to really cut down that list so I'm trying to make sure the core group is there.''
Meanwhile, Jenny - who has 12-year-old son Evan from her marriage to John Mallory Asher - hopes her and Donnie's reception will be ''elegant and pretty.''
Donnie also has sons Xavier, 21, and Elijah, 13, from his previous marriage to Kim Fey.
