Jessica Biel - Jessica Biel Cheers Husband On At First Irish Concert In Six Years
She joined more than 40,000 fans, who sang and danced along to the pop superstar's hits, backed by a jazz band.
Biel was spotted clapping and cheering at the side of the stage as her man performed in Ireland for the first time since 2007.
The Coronas stepped in to replace Timberlake's support act Jessie J, who was forced to cancel her performance due to illness.
After the concert, Timberlake tweeted, "Dublin... You sang beautifully and you danced your a**es off. What a special night. Thanks for having us."
