Jessica Simpson Single, but 'On Top of World'

July 14, 2009 — -- Jessica Simpson will have more time to focus on her upcoming reality series, "The Price of Beauty," now that she's single again.

Tony Romo broke up with Simpson last Thursday, the night before her 29th birhtday, according to People magazine.

But Simpson, who had planned to celebrate her birthday with a Barbie and Ken-themed party, already appeared to be bouncing back after the breakup.

"Barbie party didn't happen, but I turned 29 and feel like I am on top of the world yelling I LOVE GETTING OLDER!" she wrote on her Twitter page last Saturday.

The Dallas Cowboys quarterback also wasted no time lamenting the busted relationship. According to People, Romo spent Simpson's birthday at Hollywood hot spot MyHouse with 14 of his boys.

By Sunday, Simpson was waxing philosophical about love. "Everyone needs to know that hope floats ... grab the strings and pull it back to you," she Tweeted.

Three hours later, she wrote, "Falling asleep with my mom and the dogs. Please lord give all of my beautiful fans, friends, enemies, and family rest. Bring all of us peace."

A People source said that even though Simpson still loves Romo and is heartbroken over the breakup, their careers got in the way of their relationship. "He's busy with his career and she's getting ready to shoot her show ("The Price of Beauty"). They decided to part ways," the source told People.

Notwithstanding her recent breakup, Simpson seemed to be riding high after a spate of bad publicity.

The pop singer-turned-country-singer turned into a tabloid target in January when she donned the wardrobe "don't" of the year: a pair of high-waist jeans and a leopard print belt that showed off curves unseen during her "Dukes of Hazzard" days of short shorts and belly-baring shirts.

"Clearly, since we saw her last, she slayed that dragon named dignity and just spooned frosting into her mouth full time," wrote the blog "What Would Tyler Durden Do?" at the time. "Honest to God, her appearance couldn't have been any more shocking unless she had grown glow-in-the-dark tentacles."

Mean-spirited? Sure. But when Simpson's critics pulled out their claws, they also threw her more publicity than she'd seen in years.

Now, thanks to the column, inches devoted to the "fit or fat?" discussion that ensued in the weeks following her fateful appearance at a Florida country radio station's chili cook-off, the 28-year-old's got a new gig headlining VH1's upcoming reality series, "The Price of Beauty," which will follow her as she travels the world in search of what people find beautiful and why.

"I have always believed that beauty comes from within and confidence will always make a woman beautiful, but I know how much pressure some women put on themselves to look perfect," Simpson said in a statement to ABCNews.com. "I am really looking forward to discovering how beauty is perceived in different cultures and participating in some of the crazy things people do to feel beautiful."

While Simpson didn't specifically reference the weight debate that played into her scoring her new job, Jeff Olde, the executive vice president of VH1's original programming and production, made the connection clear.

"Perhaps more than any other pop culture figure on the radar today, Jessica Simpson has been the target of our obsession with beauty on both sides of the equation," Olde said in a statement to reporters. "She is a woman who can set trends and create firestorms with a single photo."
