Maxene Magalona greets sister Saab on their birthday

Maxene Magalona went all the way back to her childhood to celebrate her and sister Saab's birthday.

On a post on her Instagram account, Maxene posted a black and white photo of her and Saab as young girls. In the caption, Maxene greeted her Saab and wrote that it was her soul honoring Saab's.

Both Maxene and Saab were born on November 23, albeit in different years. Maxene was born in 1986 while Saab was born in 1988.

Maxene is just the latest celebrity sibling to give a shout-out to their sister or brother on social media. A couple of months ago, Joaquin Manansala celebrated his brother's birthday by posting shirtless photos of the two of them together.

Celebrity parents also often take to social media to greet their children. Chito Miranda posted about his son Miggy's birthday yesterday, while several weeks ago Judy Ann Santos shared photos from the 17th birthday of her daughter Yohan. A month earlier, Judy Ann also posted a sweet birthday message for her son, Lucho.
