The 'View' host and the New Kids On The Block star got engaged last month, but won't be waiting too long to tie the knot, as she hopes to do so in New York ''soon''.
She added to E! News: ''I will say fall of this year!''
The blonde beauty already knows who she wants to design her wedding dress - and it'll be more upmarket than what her bridesmaids will wear.
Asked who will design her dress, she said: ''Gucci, yes. Gucci, maybe.''
She then jokingly added: ''[The bridesmaids will wear] Forever 21, for sure.''
And the 41-year-old star will have plenty of company walking her down the aisle.
Explaining who will be bridesmaids, she said: ''[My sisters], all the comedians on the 'Dirty, Sexy, Funny' tour and Donnie's sisters.''
Donnie's family own a restaurant, Wahlburgers, in Boston so Jennie hopes his chef brother Paul will cater their reception.
She quipped: ''Why not some Wahlburgers?''
Jenny has 11-year-old son Evan from her six-year marriage to John Mallory Asher, while Donnie has sons Xavier, 21, and Elijah, 12, with his ex-wife Kim Fey, who he was married to from 1999 to 2008.
