EXCLUSIVE: Taylor Swift's Wedding Stress — How Pop Phenomenon is Tied Up in Knots… Over Tying the Knot With Travis Kelce

That means the knot-tie blowout is about three months away – probably in June – and while "Taylor's incredibly excited about marrying Travis, the logistics of it all are causing a ton of stress," shared a source.

"She's someone who likes to control every detail and keep big moments private, so the fact that their timeline and all sorts of other details have already leaked out has really rattled her to the point where she's even floated the idea of changing their plans completely to throw everything off and avoid having it turn into a circus," the insider added.

"The problem is, there aren't a lot of other options as far as their schedules go. They have a very tight timeline because it all has to fit around Travis' football schedule. Taylor totally supports him going back for another season. It's what he loves, but it hasn't made the wedding planning easy – or the honeymoon for that matter, because he's going to have such limited availability once the preseason starts."

Kelce praises his love for understanding his desire to play another season, saying: "We share the same love for what we do. Fortunately, we've had this desire since we were kids in our selective professions."

Sources believe the wedding blowout will be around June 13 at the fabulous Ocean House, a five-star resort in ritzy Watch Hill, R.I., not far from the pop star's waterfront mansion in Westerly.

The 1840 Victorian estate features 49 guest rooms and 20 suites, a putting green, croquet lawn and chapel on 13 acres with beach access and cabanas.

But the planning has the bride-to-be stressed.

"Travis handed off most of the planning to Taylor because she has a real vision of what she wants," noted the source.

"The downside of that is she's getting very overwhelmed, to the point she's having sleepless nights as a result."
