Lindsay Lohan did NOT pay the bills during her relationship with Egor Tarabasov -- in fact, it's exactly the opposite ... so say sources close to Egor.
Lindsay went on Russian TV and said Egor was a slacker who didn't contribute a dime to the relationship.
But Egor claims HE was the breadwinner between the two ... so much so he had to cover thousands of dollars in bills Lindsay racked up during the filming her latest movie.
Our source says Lindsay had access to Egor's credit card, and she used it often to snatch up gifts for herself and her entire fam. As for that emerald engagement ring ... we're told Lindsay picked it alright, but didn't pay for it. It was all Egor.
Egor's got a steady income through a bunch of investments, and even serves as director for a couple European firms ... so he's got cash to blow.
As we reported ... Egor also denies Lindsay's allegations that he abused her.
