Jessica Simpson is ''obsessed'' with her hair colour.

The 34-year-old singer debuted her newly-dyed locks via her Instagram account on Monday (04.12.14) after a two-hour visit from her go-to colourist and friend Rita Hakan.

Rita - who also styled Jessica's hair into a bob back in October - brightened her tresses to a champagne blonde hue and confessed the 'With You' hitmaker can't get enough of her new colour.

She told US magazine: ''Now that she cut her hair, she needed a cool and edgy colour. I made it a cool champagne blonde - very light, almost white, but with depth and dimension.

''[She's] obsessed.''

Rita - who also counts Jennifer Lopez and Meghan Trainor among her A-list clients - shared her top tips for maintaining the blonde beauty's glossy locks.

According to the hair stylist, Jessica swears by her 'Rita Hazan Weekly Remedy' to brighten up her look and advises blondes to take a trip to the salon for a ''Monday bleach out'' every six to eight weeks.

Meanwhile, Jessica recently admitted her husband, former NFL player Eric Johnson - with whom she has a daughter, Maxwell, two, and 16-month-old son, Ace - has given her a new lease of confidence in her looks.

She said: ''I feel stronger than ever, and Eric's unconditional love has been a reminder of the love I should give myself.

''I'm certainly not perfect, but when I look in the mirror, I'm proud of the woman I see. I'm not only someone's mother, wife, and daughter - I'm me.''
