Levi Johnston's child support battle with Bristol Palin wages on—and in the last round, Johnston's lawyer admitted the Playgirl stud's chances of finding success in Hollywood are "unknowable." Johnston shouldn't have to pay the $1,750 per month Bristol wants because his income is "erratic," say legal papers obtained by TMZ, and his chances for "increased income" are "not particularly good."
Johnston is "hopeful for an entertainment career," say the docs, and in response his babymama wishes him good luck on his job search—sort of. "Bristol is hopeful that Levi will obtain work in 2010," says a statement obtained by Radar. "Bristol expects to mediate a child visitation schedule with Levi that balances Tripp's need to be with his father with Levi's need to travel and seek work."
