Supermodel Naomi Campbell will make a guest appearance on the season finale of Ugly Betty (Thursdays at 8 pm/ET, ABC).

No word on what character she'll play. Campbell was originally slated to appear last season. That appearance was postponed to earlier this season, which was tabled due to the writers' strike.

Ugly Betty's season finale is scheduled to air on Naomi's birthday, May 22. - J.R. Whalen
