"Pretty Little Liars" season 5 cast members Ashley Benson and Shay Mitchell are clearly enjoying their summer as the ABC Family stars decided to strip down to their bikinis for their latest vacation together.

According to Us Weekly, the actresses were seen sporting two-piece swimsuits in Maui on Monday, June 30th.

The starlets took a break from their boyfriends Ryan Good (Ashley Benson's beau) and Ryan Silverstein (Shay Mitchell's man) to hit the beach on their Hawaiian vacation together relaxing on the sand and enjoying the water.

Benson, 24, took to her Instagram account to share a photo of herself and her costar on Monday.

As the gorgeous girls smiled, she simply captioned the photo with a palm tree emoji. In the snap shot both ladies were in their bikinis and cover ups with sunglasses and beach hairstyles.

While frolicking in the water Lucy Hale's costars were snapped by the paparazzi during their seven day break from promoting the current season of their show.

In the water Ashley Benson wore a basic black triangle-cut bikini top which she paired with navy blue string bikini bottoms which she accessorized with round brown aviator sunglasses.

Meanwhile Shay Mitchell, 27, rocked a light blue printed bikini with multicolor accents that she accessorized with a pair of mirrored shades.

The actresses first met on the set of "Pretty Little Liars," which debuted on the network in June 2010. It was there that Mitchell and Benson became fast friends.

Their latest trip to Hawaii is just one of their many vacations that the costars have taken together.

Back in 2013 during an interview with Seventeen magazine, Ashley Benson called Shay Mitchell one of her best friends.

The brunette beauty later returned the compliment to the blonde when she said that it was "love at first sight" when she met Benson and revealed that she is like her sister.
