Don Jr gets $20 ice cream cake for 40th birthday

He was born into wealth and has been the head of his family's multi-billion dollar organization since January of last year, but Don Jr still has a taste for the simple things in life.

The oldest of President 's five children turned 40 on Sunday, and to celebrate the big day enjoyed a special birthday song from daughter Chloe before heading out on the links with his youngest child and her brother Donnie.

Then, after working up an appetite, it was time to enjoy his birthday treat of choice - a classic Carvel balloon cake that was personalized just for him in gel writing and costs just over $20 at the nationwide chain.

Don Jr. also posted a gallery of photos from his younger years featuring himself and dad Donald before snapping a picture with his namesake that night as the two rang in the New Year at Mar-a-Lago.
