Don't cha wish your girlfriend was hot like her? Former Pussycat Dolls singer Nicole Scherzinger showed off her sexy figure on Friday, Aug. 9, as she headed to X Factor bootcamp in a revealing cutout dress that exposed her toned midriff and long legs.

Scherzinger, 35, looked fit and healthy in the striped frock, which featured a side cutout and asymmetrical hem. She completed the ensemble with white open-toed booties, braids, and oversized sunglasses.

The outing came just two days before reports surfaced that the star had reunited with ex-boyfriend Lewis Hamilton. On Sunday, Aug. 11, the Mirror's Sunday People claimed that Scherzinger and the Formula One racer had reconciled at her Beverly Hills mansion.

"They desperately want to be together, but they know that from now until Christmas is going to be really tough," a source told the U.K. paper, citing the couple's busy work and travel schedules. "They're both willing to give it their best shot and try to make a success of it, though. They love one another dearly and have deeply missed each other since they split."

As previously reported, the "Buttons" singer and her British ex dated on and off for five years before splitting earlier this summer. Shortly before their breakup, Hamilton hinted that there might be a proposal on the way. "Hopefully in the near future," The Sun quoted him as saying. "Maybe before we get to six years."

"We are both passionate," he told VH1 during a 2012 episode of Behind the Music. "Together we've created a great bond."
