A playwright is suing brain cancer-stricken Valerie Harper, claiming the beloved “Rhoda” actress ruined his production - by not telling anyone she was deathly ill. Matthew Lombardo wants Harper to fork up $2 million - $500,000 in addition to $1.5 in punitive damages, according to a lawsuit cited by TMZ.

Harper announced last March that she had been diagnosed with brain cancer and had just months to live. But she went to compete in ‘Dancing with the Stars’ past fall. While America cheered her fight for life, Lombardo said Harper was wrong for keeping her cancer to herself up until March 2013.
