Talk about stealing Hanna’s (Ashley Benson) thunder! On Wednesday it was revealed that another pretty little liar has gotten engaged: actress Sasha Pieterse.

“The best day of my life,” the 19-year-old actress, who portrays Alison on the hit Freeform (formerly ABC Family) series "Pretty Little Liars," captioned a sweet photo of her and her fiancé Hudson Sheaffer together.

In the image that Pieterse posted to her Instagram account, she looks overwhelmed with joy as she grabs her soon-to-be husband’s face (while also showing off that rock on her left hand!). But, according to reports, the blond-haired starlet wasn’t the only one overcome with happiness on that momentous day. Pieterse’s fiancé shared a photo of his own that revealed the very moment he got down on one knee to pop the question.

“She said yes!!!” Sheaffer, 26, said before thanking photographers Jonnie + Garrett for capturing their dream desert proposal. According to reports, the couple, who share two dogs together, were dating for a little over a year before getting engaged.

The exciting news comes shortly after it was revealed who would be playing the role of Hanna’s fiancé in the upcoming installment of "Pretty Little Liars." But unfortunately for Haleb shippers, the man who asked for Hanna’s hand in marriage was not her long-time boyfriend Caleb (Tyler Blackburn).

TVLine revealed that Australian actor David Coussins had actually landed the coveted role of Hanna’s fiancé, Jordan. And it looks like viewers will get to meet the recurring newcomer when “Pretty Little Liars” returns for the second half of Season 6 in 2016. Fans will also learn who Alison is married to when the series makes its way back to the small screen. During the summer finale, it was teased that Alison tied the knot sometime during the time jump after the Rosewood teacher (yes, Alison is now a teacher) wrote down the name "Mrs. Rollins" on her chalkboard.

Marlene King, mastermind behind the small screen drama, confirmed to TVLine that Alison is married -- and to a doctor nonetheless! "That’s all I’ll say," she stated.

Now ... which liar will be getting hitched next?

“Pretty Little Liars” will return to the small screen with its Season 6B premiere on Tuesday, Jan. 12 at 8 p.m. EST on Freeform.
