Her wedding won't be quite as big a deal as her sister's, but this is still big news!

Pippa Middleton is engaged to her boyfriend James Matthews, and she told reporters outside her London home on Tuesday that she "couldn't be happier." Aww!

"Miss Pippa Middleton and Mr. James Matthews are delighted to announce they became engaged on Sunday, July 17 and plan to marry next year," the pair said in a statement.

"They make a wonderful couple and we wish them every happiness together," her dad Michael Middleton said in his own statement. "The Duke and Duchess of Cambridge are absolutely delighted with the news," a Kensington Palace spokesperson added.

Matthews popped the question on a romantic vacay in the Lake District in northwest England. The pair first began dating in 2012 before splitting, and then the socialite went on to date Nico Jackson for three years before rekindling the flame with Matthews in 2015.
