Britney Spears walked down the aisle on Saturday (23May09) - to serve as an "honorary" bridesmaid at her cousin's wedding.
Spears and 18-year-old sister Jamie Lynn, who brought along her 11-month-old daughter Maddie, were members of their cousin Laura Lynne Covington's wedding party at the First United Methodist Church in Amite, Louisiana.
The pop star tried not to attract attention as her older brother Brian escorted her down the aisle - but guests couldn't help but notice Spears looked healthy and happy at the joyous event.
One guest tells People.com, "When her brother walked her down the aisle, she looked stunningly calm and beautiful. She was very pretty, low-key. She was not the centre of everything, just pretty and calm and collected.
"There was no fanfare. With all the star power Britney and her family command, it was still the bride's day."
