Britney Spears [ tickets ] continued her mini-tour of House of Blues venues last weekend, thrilling audiences in in the Orlando area and Miami despite a few technical difficulties.

During Saturday night's (5/19) show in Lake Buena Vista, FL, Spears' lip-syncing ways were made obvious when her background track skipped, forcing her to improvise by turning away from the audience, according to People magazine. Despite the glitch, fans, some who waited in line for hours, ate up the 14-minute performance.

The next night in Miami, Spears suffered a wardrobe malfunction--her bejeweled bra coming undone to reveal a pink bra underneath. She attempted to continue "singing" while holding the garment in place but eventually ran off stage, leaving her backup dancers to finish the performance, People reported. Once again, the audience didn't seem to mind.

However, Spears didn't make many fans on her trip to Florida from Los Angeles. According to various reports, the pop star delayed her would-be flight nearly an hour after she demanded to be let off the airplane at the last minute because the seats were not made of leather.

Spears put the wheels in motion to resume her music career early this month when she performed her first public concert in nearly three years at the House of Blues in San Diego, CA. The embattled singer has been under scrutiny in recent months following her divorce from dancer/rapper Kevin Federline and her subsequent rehab stint in Malibu, CA.

The 25-year-old mother of two recently posted a letter to fans at her website, thanking them for their prayers.

"I am so blessed that you care enough about me to be concerned and will continue to live in this brighter state with all of you by my side during this trying time," Spears wrote alongside a provocative picture of herself. "We are all lights of the world and we all need to continuously inspire others and look to the higher power. You are all in my prayers."

Spears checked herself into rehab earlier this year after tabloids spent weeks documenting her erratic behavior.
