How Long Have Sasha Pieterse & Hudson Sheaffer Been Dating? The 'PLL' Star & Her Fiance Go Way Back

On Pretty Little Liars, Alison DiLaurentis tends to keep her relationships a secret. Excluding Lorenzo, Ali only refers to the guys she's dated by nicknames, whether Beach Hottie or Board Shorts. (Side note: Who is Beach Hottie?! Fans still don't know.) But in real life, actor Sasha Pieterse is very open about her relationship — and it's absolutely adorable. On Tuesday, Pieterse got engaged to longtime boyfriend Hudson Sheaffer. It's hard not to be happy for the PLL star, who seems like a sweetheart in real life, despite the mean girl she plays on TV. She and Sheaffer have been together forever — or so it seems. So, how long exactly have these two been dating? It turns out it's been several years now.

Despite my in-depth Google searches, there's no actual timeline of how long these two have been together. Instead, I took to Instagram and browsed Pieterse's photos. Fans who follow the 19-year-old know that her new fiancé frequently stars in her selfies. Whether posing with their Christmas tree or going on roadtrips trips, they're always together. The pair even has two dogs together and refers to themselves as a "family." Based on my digging, Sheaffer began making appearances three years ago, so I'd guesstimate that they've been together at least three years now. Granted, appearing in photos together doesn't confirm that's when they began dating, but they did look snuggled up and coupley. Plus, given the 8-year age difference between them, maybe they kept their relationship under-wraps in the earlier stages.

Since these two really do have quite a history together, here's a round-up of Pieterse and Sheaffer's sweetest moments over the years.
