'Pretty Little Liars' Star Sasha Pieterse Is Engaged: See The Romantic Pics

Sorry, make that "engAged."

When "Pretty Little Liars" returns for its seventh season on January 12, Sasha Pieterse will have something in common with her onscreen alter-ego, Alison DiLaurentis: they'll both be rocking some bling on their left hands!

Pieterse announced on Instagram Tuesday night (December 22) that her longterm boyfriend, Hudson Sheaffer, had popped the question -- and this being the generation of "A," all of it was caught on camera (by photographers Jonnie + Garrett):

Such joy! Sheaffer seems to be over the moon about it.

The 19-year-old "PLL" staple isn't the only one with some nuptials on the way, of course. Her costar Troian Bellisario became engaged to "Suits" star Patrick J. Adams in 2014. So in other words -- Lucy Hale, Shay Mitchell, Ashley Benson, and Marlene King have some shopping to do.
