They're letting her know where she needs to be and when she needs to be there. They have a driver for her', the source told the Daily Mail.'That's how it is with everybody, even the people really close to them. When they get to where they need to be, they're told where they're going next. While her son Travis Kelce and soon-to-be daughter-in-law Taylor Swift are prepping for their NYC wedding in style, Donna Kelce came swiftly back down to earth as she jetted into the city on Thursday Swift and Kelce are just hours away from the commencement of their wedding weekend. Above, at the iHeart Music Awards in March'So she doesn't really know a lot about the plans, because she hasn't been told. I think that's their way of making sure that things aren't leaked. Everyone is on a "need to know" basis.'I think she likes it that way. It's not a stress. Travis told her what type of clothes she'd need and basically everything is going to be easy for her. She's very excited to experience it as it happens, with some mystery along the way.'It is understood Donna immediately rushed to MSG after landing. The Daily Mail has contacted representatives for comment and has yet to hear back. While a plethora of A-listers have descended on NYC for the wedding, Travis's father Ed and brother Jason, along with wife Kylie, have yet to make a public appearance. Donna's solo stroll comes after insiders dished to the Daily Mail on how Swift and Kelce have shut out their parents, instead arranging the big day between themselves and a wedding planner.'Both sets of parents are all really happy and think getting married is the right thing for them to do because they're old school and wanted him to put a ring on Taylor's finger,' an insider told us. 'But none of them are involved in the wedding planning, although surprisingly Travis is.''Taylor's not the official wedding planner, but most of the ideas are hers. She's used to taking control. This will be her big day and along with Travis she'll be the mastermind,' the source continued.
