Jasha

Jasha is the real-life pairing between Janel Parrish (Mona Vanderwaal) and Sasha Pieterse (Alison DiLaurentis). They star alongside each other on Pretty Little Liars: The Perfectionists.

Background
Janel and Sasha met in 2010, when they both book their respective roles on Pretty Little Liars. The two didn't have many scenes together in the first season, and therefore, didn't see much of one another. However, as Sasha was in the show more, they got to know each other better and see more of one another. They then became friends and started hanging out outside of the set. Janel has stated that she was shocked to learn of Sasha's actual age to the latter's maturity-level.

In 2012, they both attended ''Victoria's Secret: What Is Sexy? Party'' in Beverly Hills. They represented part of the Pretty Little Liars cast at the event, alongside Keegan Allen and Holly Marie Combs.

In 2016, they both participated in the Pretty Little Liars RevelAtions Con in Germany together. They also did a few panels with one another, they were answered fan questions. When Sasha was asked about baby-names for her and Hudson Sheaffer's (her boyfriend and later fiancé) first child, Janel jokingly stated that Janel would be a great name for a girl, and Janelo for a boy. This made Sasha laugh, and she was also able to avoid answering the question or talking about having children. At the same con, they sang the PLL theme song, together.

In 2017, Janel was present at Sasha's twenty-first birthday celebration where they drank alcohol together for the first time. Later that year, they attended Paleyfest together and did a panel together where they talked about Mona and Alison's relationship. Janel also congratulated Sasha on her engagement to Hudson Sheaffer.

At a con in 2017, they read an iconic Hanna and Mona scene together after Sasha revealed that she auditioned for the role of Hanna first.

In 2018, Sasha congratulated Janel on her engagement to her long-time boyfriend, Chris Long. Later, it was announced that they would star alongside each other in the Pretty Little Liars spin-off, Pretty Little Liars: The Perfectionists. They also briefly reunited on the Warner Bros. lot when they visited Troian Bellisario and I. Marlene King on the set of Famous In Love.

Janel wished Sasha a happy birthday on Instagram saying, "Happy birthday, sweet Sasha. Birthday hugs SOON". They later took pictures together during the table read for The Perfectionists, and had dinner together that night, when Janel joined Sasha and her fiance, Hudson.
