Heidi Montag has praised Spencer Pratt for the ''best 8 years of my life (sic)''.

The former 'The Hills' star gushed over her beau in a message online on Friday (21.11.14) to celebrate their sixth wedding anniversary.

In a post on her Instagram account, the 28-year-old beauty wrote: ''Happy 6 year Anniversary! Thank you for the best 8 years of my life, 6 married! My heart, my soul, my love! So excited for the next year and all the ones to come! This has been the best yet! (sic)''

The television personalities celebrated their relationship with a photoshoot in California's Napa Valley, after which Heidi's 31-year-old husband also took to his social media account to praise his lover.

Writing on Twitter, he said: ''Happy Wedding Anniversary to my miracle wife @heidimontag thank you for staying married to me for 6years! (sic)''

The couple's celebrations come just days after Heidi vowed to never have a cosmetic operation again, after famously going under the knife for 10 procedure in one day in 2010, including operations on her breasts, nose and chin.

She told 'Extra': ''I'm just done with all of it. I'm going to age gracefully and bow out.

''I disliked myself so much I literally chopped up my whole body.
