David Beckham has added another meaningful tattoo to his growing collection and this time it's in honor of his son Brooklyn.

The 40-year-old soccer hunk got "Buster" tattooed on his neck, on the opposite side of the "Pretty Lady" one he recently added for his daughter Harper.

"I've always called Brooklyn (Buster) since the day he was born," Beckham captioned the photo. "Love you Bust."

Just last month, Beckham took to Instagram once again to share his love for his 16-year-old son. "Something tells me I love this not so little man so much," he captioned a black and white photo of the two. "Growing up fast into a perfect gentleman and hiking buddy...I love you big boy."

Beckham is extremely proud of his children Brooklyn, Romeo, 12, Cruz, 10, and Harper, 4, who he and his wife Victoria Beckham are always raving about. He even stood up for his daughter last month when an article was put out slamming his parenting skills for still allowed his daughter to use a pacifier. Beckham quickly shut them down, though, pointing out that Harper was sick, needing her pacifier to comfort her, and that "those who criticize think twice about what you say about other people's children because actually you have no right to criticize me as a parent."
