American Idol fans were totally wowed when they tuned into Thursday night's episode, and not just by the contestants' performances.
Jennifer Lopez, who has one of the most enviable wardrobes on television, wore her most dazzling look yet: a gold star-print sequined long-sleeve Dolce & Gabbana dress. She paired the curve-hugging design with Gucci sandals and a ultra smoky eye.
The 43-year-old mom-of-two took her beau Casper Smart, 24, to work on Wednesday, where he sat in the audience while the show was being taped.
The backup dancer, warmly greeted Lopez's fellow judges Randy Jackson and Steven Tyler -- and was the brunt of a good-natured joke from host Ryan Seacrest, who pointed out Smart chatting with two pals in the audience during a commercial break.
"Which of these three guys is Jennifer's boyfriend?" Seacrest said "Or is it the one who's shorter than Ryan Seacrest?" Lopez doubled over laughing as Smart looked a bit embarrassed as the audience cheered.
