As the wedding date of Prince Harry and Meghan Markle is fast approaching (FYI - it's less than 100 days away now), we've been deliriously obsessing over all of the crucial details... What the gown will look like, who she will she wear, how she will do her makeup, etc, etc, etc.

And while we can only make educated guesses on the above at this stage, we've got some pretty solid insight about her potential beauty look for the big day, from a very reliable source - her former hairstylist and makeup artist, Lydia F. Sellers. And considering she was her stylist for over two years (which is practically a lifetime in Hollywood), we're treating it as sold truth.

In an interview with Refinery29, Lydia revealed she thinks Meghan will style her hair down over an updo. "We styled her hair down a lot-that's the look she gravitates toward. It could be straight or wavy or anything else, but she likes it down. So if it wasn't a royal wedding, I think that's what she would do."

However, considering it is a royal event, Lydia says there's a possibility that Meghan may opt for a more traditional style, like a royal-approved 'sleek and elegant chignon', which we all know is a universally-approved Princess hairstyle. Not to mention, Kate Middleton also wore her hair in a now iconic (demi) chignon when she married Prince William in 2011, so maybe it's a royal rule of some sort? We guess only time will tell.
