Sen. Kelly Ayotte (R-N.H.) will be helping out former Sen. Scott Brown (R-Mass.) this weekend, but not in an explicitly political manner.

As the NH Journal first reported Thursday, Ayotte will preside over the nuptials of Scott Brown's 23-year-old daughter, Arianna, and her 23-year-old fiancée, who once served as an intern in Brown's Senate office.

Brown is running for the Republican nomination in the hopes of unseating Sen. Jeanne Shaheen (D-N.H.).

The wedding will take place at a winery in Lee, N.H.

"I consider it a great honor to have been invited to perform this ceremony, which will join the lives of two special young people -- Arianna and Jim. I'm looking forward to celebrating on Sunday," Ayotte said in a statement.

An Ayotte spokesman said the wedding will be the first she has ever officiated.

The senator endorsed Brown in May, though the two have differed on policy matters.

A WMUR/University of New Hampshire poll released Tuesday shows Shaheen with a 12-point lead over Brown in a hypothetical head-to-head match-up.

Though Brown's summer will undoubtedly be filled with campaign events, he'll also be kept busy with family: his older daughter Ayla, who was a semi-finalist on the fifth season of "American Idol," is getting married in Nashville, Tenn. in August.
