Reps for Sandra Bullock and Jesse James have been interviewing divorce lawyers, according to TMZ.com.
Bullock's front-runner: Lance Spiegel, who has handled divorces for Charlie Sheen, Heather Locklear and Michael Jackson, according to the site.
James - who will not be initiating the divorce - also is having his business people contact several lawyers, TMZ claims.
No papers have been filed yet.
Bullock's rep tells UsMagazine.com the report "completely false."
Last week, James, 40, publicly apologized to Bullock, 45 -- to whom he has been wed for nearly five years -- after tattoo model Michelle McGee claimed she had a fling with him as Bullock filmed her Oscar winning role in The Blind Side last year.
Friends tells UsMagazine.com they doubt Bullock will reconcile with James.
Says one pal, "Knowing the kind of person she is, I’d be shocked if she contemplated going back to him."
