Despite Access Hollywood's previous report, which said the two had been dating for three years, we've now learned the two have been together for "less than one year," according to a source.
Mel stepped out with the 39-year-old brunette at the "X-Men Origins: Wolverine" premiere on Tuesday evening in Los Angeles, their first public outing as a couple.
According to the Daily Mail, Grigorieva, a singer, is signed to Mel's recording label, Icon.
She previously dated former James Bond star Timothy Dalton, with whom she has a 12-year-old son named Thomas.
As previously reported on AccessHollywood.com, earlier this month, Mel and his wife, Robyn, officially filed for divorce in Los Angeles court. They separated almost three years ago.
