While whooping it up in Vegas for her 34th birthday, reality TV star Holly Madison said she’s eager to have more children.

The former girlfriend of Playboy magazine founder Hugh Hefner said 2014 will be all about work and expanding her career, but next year she wants a little brother or sister for her 9-month year old daughter Rainbow Aurora, who’s getting cuter by the day, she said.

“We definitely want more kids sometime soon,” said Robinson, in an interview with Us Weekly “Most of next year I’m going to be concentrating on working and stuff, but hopefully by the end of next year.

In addition, Robinson said she’s also taking 2014 to do some organizing in her personal life.

“[My goal this year is] to get organised,” she explained, “Because my life is disorganization nation right now, I’m an absolute mess! “Literally my house is a mess. Figuratively, I’m just unorganized in every way.”

The “Girls Next Door” star Tweeted some beautiful photos of her birthday gala at Vegas’ Palms Casino Resort, where she wore an eye-catching sequined dress and treated herself to a three layered rainbow cake. Reportedly, both the dress and the cake were gifts from her husband, Pasquale Rotella, who she married in September of 2013.

But Madison wasn’t the only happy camper in the room, as she took the time to pose with many of her adoring fans, while also dancing the night away with glow sticks in hand, which only added to the birthday celebration.

The blonde bombshell rose to fame in 2003 when she was featured as “Cyber Girl of the Week” on Playboy’s website, and when she appeared on “The Girls Next Door” and ABC’s “Dancing with the Stars.” She also had a relatively successful run with her reality show “Holly’s World” in 2009.

It seems the Astoria, Ore. native will have a busy 2014, as she develops new projects and makes plans to add to her family.
