Madonna shares sweet birthday message for son Rocco

Madonna shared a sweet birthday wish for her son Rocco Ritchie with a heartwarming tribute.

The Material Girl singer, 64, shared a rare photo montage of son Rocco Ritchie for his 23rd birthday on Thursday set to The Beatles song, "Here Comes the Sun."

"Happy Birthday Dearest Rocco……." the singer wrote. "From the day you were conceived, Life with You Has been an adventure. From Your Pre Mature Birth to your love of Skate Boarding, Dirt Bikes. Break Dancing, Parkour, Graffiti and all Adrenaline Provoking activities!"

"You have made me worry— possibly more than any other person on the planet. But You have taken the road less traveled by and that will make all the difference! Nothing gives me more Joy then to watch you grow as an artist! To quote your favorite painter Lucian Freud— “What do I ask of a painting?"

"I ask it to astonish, disturb, seduce, convince!” Keep Walking Down Your Own Road. I’m so proud of you! she concluded the post.

Madonna is also mom to twins Estere and Stella, who turn 11 later this month, Mercy James, 16, and David Banda, 17 with ex-husband Guy Ritchie, and Lourdes Leon, 26, with ex-husband Carlos Leon.

Though Rocco keeps a fairly low profile, he was spotted with Banda near his mom's NYC apartment in July following her hospitalization from a bacterial infection. The singer later posted an update thanking friends, family, and fans for their support on Instagram.
