Tatum and Dewan met on the set of Step Up, in which, ironically, they were both each other's love interests, and began dating after the filming was over. They both have similar backgrounds in modelling, however Tatum was reportedly intimated on set given that he was without any professional dance training unlike his co-star and would be wife Dewan.
The couple have recently starred opposite another again in the film 10 Years.
They got engaged in September 2008 in Maui, Hawaii.
The pair married on 11th July 2009 at Church Estates Vineyard in Malibu, California.
They now have a production company 33andOutProductions and their debut documentary Earth Made of Glass premiered in 2012 at the Tribeca Film Festival.
Their daughter, Everly Elizabeth Maiselle, was born in London, England in 2013 and the couple have a dog together, Meeka.
Dewan is a vegan, however she has allegedly raised her daughter to eat meat and is allowing her to decide when she gets older if she wants to follow in her mother's footsteps.
Happy Wedding Anniversary Channing and Jenna!
