"[Bridget] has been helping me plan details and stuff – she's been helping out a lot," Wilkinson, 23, told PEOPLE Tuesday at the launch of Bridget's Sexiest Beaches, the new Travel Channel show starring Bridget Marquardt.
Marquardt, who along with fellow Girls Next Door costar Holly Madison is among Wilkinson's six bridesmaids, helped decide the color for the dresses. "At first I thought the color was pink until Bridget tried on a lavender dress and I was like, 'Oh! The color is lavender because she looked gorgeous,' " says Wilkinson.
His & Hers PartyAnother celebration is also in the works – the bachelorette party. "[Hank and I] doing a joint one," says Wilkinson of her Philadelphia Eagles fiancé. "We're thinking about a getaway to Palm Springs. He's going to play golf, and me and my girls are going to get massages."
And what about a party? "Everyday will be one big party!" she says. "C'mon, he's got a lot of guys I got a lot of girls. Why not put them all together?"
One thing she hasn't given much thought to, though, is a bridal shower. "I'm not too into a bridal shower," says Wilkinson, a self-professed tomboy. "I don't like to hang out with girls for so long I'd go crazy. So I just want to keep it the basic stuff."
Relocation NewsBut the bride-to-be is making already plans for after the wedding. 'After we get married I'm going to go out there to Philly with him and support him."
As for a family, Wilkinson says they want children soon – but not too soon. "There's so much out there we want to go see. We want to go to Paris, all around the world before we have kids."
