Viagra cured a 70-year-old construction executive's impotence - too well, his former companion says in a lawsuit.

Roberta Bernardo, also identified in published reports as Bobbi Burke, is suing Francis Bernardo for $2 million, claiming the impotence drug led him to infidelity.The 61-year-old woman said their 10-year relationship fell apart when Bernardo left their luxury condominium May 5 with a bottle of Viagra he'd had for two days.

Her palimony complaint, filed May 15, said he left a note boasting of his renewed vigor and saying their relationship was over.

"He's rejuvenated and can get back out there," she told the New York Post. "At 70, I guess he figures he's going to party until he goes."
