In less than two weeks, Pippa Middleton will be a bride!

On Saturday, May 20, Kate Middleton’s sister is set to walk down the aisle with her fiancé, James Matthews. But, no one said the wedding planning has been seamless.

“There have been a few nervous tears,” a friend revealed to Life & Style. “And she hasn’t been sleeping well.”

“Pippa wants the day to be perfect,” another close friend added. “But as any bride will tell you, it’s really never that simple.” The 33-year-old is worrying about everything from her dress not fitting to the limited guest list causing a frenzy.

Although Pippa has implemented the “no ring, no bring” rule, limiting plus-ones to married and officially engaged couples at her nuptials, her big sis Kate has asked her to make one exception for Prince Harry’s new girlfriend Meghan Markle.

It’s unclear whether or not Meghan will attend the ceremony or just the reception, but a friend reveals she “has been leaning toward staying out of sight at the ceremony.”

Regardless of the hecticness leading up to the nuptials, “She’s deeply in love with James and knows all the drama will be worth it. She’s so happy to be staring the rest of her life with the man she loves.” We can hardly wait for the big day!
