Another royal wedding? Be still our beating hearts! We don't think we could take all that excitement! Well, thankfully for our blood pressure, the potential nuptials in question wouldn't technically be a royal wedding... More like a royally-related wedding! Kate Middleton's brother, James Middleton, might be soon tying the knot with his sweetheart of three years, English model Donna Air. Think the Duchess of Cambridge will be serving as a royal bridesmaid? One can only hope!

The U.K. magazine Fabulous recently sat down with Donna Air, where the subject of marriage came up because duh of course it did. And from the sound of it, there definitely could be wedding bells in the near future for the Middleton family. "I feel like I've already had a marriage of sorts. But would I like to have an official one? Yeah. Hell, why not!" the blonde beauty declared. "I always say you have to try everything once," Air continued. "Marriage is important and it's a nice foundation if you have children."

Having Prince William as a brother-in-law can't be easy when you're thinking of proposing. We mean, James Middleton probably doesn't have a 12-carat blue sapphire heirloom engagement ring lying around, right? But the British model sounds like a rather low maintenance almost-bride-to-be. In fact, according to Air herself, a big grand wedding (ahem, like that her sort-of sister-in-law's) just isn't her style. "The thought of a big wedding...," she mused. "I would rather just go for lunch!"

So while it doesn't sound like another over-the-top Alexander McQueen wedding dress is in the works for this fam, we're sure that the Duchess of Cambridge will slay in whatever bridesmaid dress her to-be sister-in-law ends up dressing her in. (She is going to be a bridesmaid, right? Right.) She can even steal some tips from the queen of all bridesmaids, Pippa Middleton, if she needs a few pointers. Remember how she rocked that white sheath like nobody's business? Le sigh...
