SYLVESTER STALLONE’s mother is going under the knife in a dramatic bid to save her life.

Sly’s  91-year-old mother Jackie, has suffered a heart attack, reports

She will have open heart surgery at an L.A. area hospital Monday morning.

The Rocky star’s tireless mom, who has worked as an astrologer, launched a skincare products line, and hobnobbed with celebrities for years, reportedly stayed overnight in the hospital after the heart attack and her husband, Dr. Stephen Levine, has been by her side.

Sadly, it’s been a rough past few months for “The Expendables” legend.

Sly’s 36-year-old son, Sage Stallone, died of a heart attack last year.

And the actor’s half sister, Toni, died of lung cancer a month later.
