Zac Efron has hearts soaring, flying after sharing a snap on Valentine's Day.
In celebration of Feb. 14, the High School Musical alum posted a photo to Instagram of himself reading to his 3-year-old half-sister, Olivia. Of course, he's shirtless in the snap, too. Alongside the pic, he simply wrote, "My valentine."

The 35-year-old's snapshot with his little sister comes almost two months after he shared another adorable photo with Olivia in honor of her birthday on Dec. 25. For those series of sweet pics, of which he is seen cradling her in his lap, Zac wrote, "Happy bday lil sis." (Olivia is Zac's dad and stepmom's daughter.)
