"Pretty Little Liars" star Lucy Hale showed the world how much she cares about her boyfriend with an Instagram post calling him her "heart."

Hale usually does not flaunt her relationship she has with Anthony Kalabretta, E! News notes. But she was definitely feeling the love this week.

The couple was spotted on the beach back in June while vacationing in Hawaii, according to Us Weekly. Hale did not post any pictures of her beau to social media at the time.

"They met through mutual friends and bonded over a lot of things -- just having fun and their shared love of music," an insider said of the couple. "She has a thing the musicians."

The insider also noted Hale is happier than ever while enjoying her hiatus from the ABC Family hit show and building her relationship with Kalabretta.

Hale and Kalabretta were first spotted at a Dodgers game on June 18. Prior to their relationship, the 26-year-old brunette star was linked to Lawson drummer Adam Pitt.

Meanwhile, the star who plays Aria in "PLL," has also become an advocate for teaching children about meningococcal meningitis, PEOPLE reported.

Back in May, Hale teamed up with Voices of Meningitis for its "Boost the Volume" campaign where they challenged high school a capella groups to sing a mashup of American Authors' "Best Day of My Life" and One Republic's "Good Life."

While the winning group got a chance to sing with Hale, her biggest goal was to spread the awareness of the deadly disease to teens.

"I'm very aware of who supports me and who my fan base is, and that's teens," Hale said at the time. "Teens are the ones that are at risk here. Oftentimes, I don't get to lend my voice to something that can change a life. Although it's a rare disease, it's one too many. It's always one too many."

"Pretty Little Liars" returns in the winter for the second half of Season 6.
