Almost six years into marriage and with a three year-old kid, you would expect that the honeymoon period might be over for Justin Timberlake and Jessica Biel.

Biel’s Instagram comments would suggest that's definitely not the case.

The The Sinner star couldn’t resist making her feelings towards her husband known on the photo-sharing app. Under a picture of the 37 year-old ‘Can’t Stop The Feeling’ singer working on his book, the 36 year-old mother to Silas wrote, ‘my wordsmith at work. Always in awe of your big…brain.’

The 'Rock Your Body' singer's first book , Hindsight & All the Things I Can't See In Front of Me, will, according to his website, 'give readers a peek into Timberlake's creative process through an intimate collection of images from his personal archives that range from childhood to present day.'

To be honest, a massive intellect is something we too find attractive in a man, and looking at Timberlake's roster of hit songs, it's clear his is huge.

Last month the talented and beautiful couple were super adorable on the Emmy's red carpet. Though Biel didn't win on the night for her Emmy-nominated role in The Sinner, the pair looked super loved-up, sharing smooches for the cameras after the award ceremony.
