Justin Timberlake serenaded Jessica Biel at his concert on Sunday (05.05.13).

The 'Suit & Tie' hitmaker only had eyes for his wife of seven months while performing an intimate gig to 3,000 fans at the Roseland Ballroom in New York City, singing his most romantic lyrics to the 31-year-old beauty.

Jessica was sitting with Hollywood pals Olivia Wilde and Jason Sudeikis at the concert and her singer spouse was clearly feeling inspired by her presence - crooning the lyrics to his hit song 'Mirrors' directly to her.

A source told the New York Post newspaper: ''Jessica was sitting in the balcony with Olivia Wilde and Jason Sudeikis. When Justin opened the show, he kept looking right at her. And when he sang 'Mirrors,' he sang the lyrics directly up to Jessica.''

The song boasts lyrics including: ''I don't wanna lose you now, I'm lookin' right at the other half of me.''

It's not the first time the newlyweds have shared a romantic moment mid-concert; Jessica - who often supports Justin in the crowd at his gigs around the world - was seen affectionately singing and dancing along to the singer's biggest hits, including 'Like I Love You' and 'SexyBack', at the 32-year-old star's post-BRIT Awards gig in London in February.

An onlooker said at the time: ''She knew the lyrics to all of his songs. It was so sweet. She was looking at him very lovingly.''
