For Amber Alena, bigger is better.

The 24-year-old cam model and adult film actress says she increased her breast size from a B cup to a whopping N cup and has never felt happier — despite spending a fortune.

Alena says her decision to go under the knife for breast implants was not for her profession, but rather for her own “benefit and happiness.”

“I got them done for myself and no other reason,” she says. “My chosen professions could easily be done without surgical enhancements.”

The Seattle resident says her N-cup breasts do not cause her any pain or discomfort, and she has found ways to support the massive implants.

“I do a lot of exercises to help,” she says. “My breast size is considered very large, but there are other women who have much bigger breasts.”

Alena says she had a series of three breast augmentation surgeries — first to a D cup, then a J before eventually reaching the N cup — which cost around $25,000 total.

But the cost of surgery was a small price to pay for Alena, who said she wanted bigger breasts since she was 17 years old.

“When I was much younger, it hurt my feelings because I couldn’t control how I was born to look,” she says.

Alena says she was frequently judged by others while growing up because her “facial features and aura always generated a love/hate view,” but she is learning to ignore haters and be confident.

“I do wish some people could learn to be less judgmental,” she says, “but now I no longer care how others perceive me.”

With 328,000 followers on Instagram, Alena isn’t afraid to post risqué photos showing off her new assets and tunes out the harsh criticism.

“As long as it makes you happy, f–k what anyone else thinks, because life is too short to care about others’ opinions,” she says. “There will be people who love you for you, with or without surgery.”
