Holly Madison made best friend Angel Porrino's dream come true when she bought her a boob job for her 21st birthday in the July 18 episode of Holly's World. "It was something I always thought about," Angel tells Life & Style exclusively about her pal and personal assistant. "I had 50 year-old boobs at age 20," the single mom says about her A-cup breasts, which never regained their natural shape after the 2009 birth of her son, Roman. "It was bad."

"I've known Angel since she was 18, and she's always been talking about getting a boob job," Holly Madison tells Life & Style. "It's really exciting to be able to buy a friend a present that she's super, super excited about," says Holly, who paid for the gift with the money she earned hosting Angel's birthday party at Tao in Las Vegas.

And Angel is a satisfied customer. "They're proportionate to my body," says the bubbly bombshell about her new D-cup breasts. "I'm just more confident, and I don't think there's anything else about my body that I would want to change."

The results of Holly's life-changing birthday gift will be revealed in the season finale of the E! reality series on Aug. 1. For more from Holly and Angel, pick up this week's issue of Life & Style, on newsstands now!
