Booble, which based the contest on its popular fan-sign program, in which adult models place their boobs between the "B" and "ble," said it is "ecstatic" to have Cruz as its June winner.
Cruz, a two-time Booble Girl of the Month, topped Carmen Luvana, Sandee Westgate and Dawn Allison for the win. As a winner of the monthly contest, she is in the running to be Booble Girl of the Year, which comes with a $5,000 prize.
"I was surprised I won again," Cruz said. "Thank you to everyone that voted for my Booble boobs. I look forward to running for the Booble Girl of the Year once again."
The Booble Girl of the Year field also includes Nikki Benz, Shyla Stylez, Sophie Dee, Vicky Vette, Sabrina Deep, Mariah Milano, Trina Michaels, Brandy Talore, Tera Patrick and Heidi Mayne.
Cruz has appeared in national and international fitness magazines such as Ironman, American Curves and Musclemag. She runs Fantasy Girl Entertainment with her partner Brandon Michaels.
The Booble Girl contest is open to models who are at least 18 years old and have a website or cam show, appear on a website or cam site, or appear in at least one commercially released DVD. Models must use the fan sign provided by Booble.
Booble users select the monthly winners, who receive $500 and entry into the annual contest.
