Party girl takes Tinseltown by storm at age 87

REINCARNATION guru Shirley MacLaine’s getting a new martinifueled life as her career and party circuit come back from the dead at age 87, sources say!

After years in the weeds, the 1984 Terms of Endearment Oscar winner, who divides her time between L.A. and New Mexico, has landed plum roles on Hulu’s Only Murders in the Building series and the upcoming comedy American Dreamer with other projects in the pipeline.
