The mystery behind L’Wren Scott’s tragic suicide deepened Wednesday, as the designer’s newly revealed will shows she wasn’t drowning in money woes when she took her own life last week — but was instead sitting on a $9 million fortune.

Although reports indicated Scott’s design business, LS Fashion Ltd., was $5.9 million in the red, her will bequeathed her $8 million condo, which she owned under a corporate name, to the love of her life, Mick Jagger.

The ex-model also left the already ultra-rich Rolling Stones frontman a $1 million trove of other valuables.

Her family, meanwhile, got nothing.

“I give all my jewelry, clothing, household furniture and furnishings, personal automobiles and other tangible articles of a personal nature … to Michael Philip Jagger,” Scott’s will says, according to court papers reviewed by The Post Wednesday.

Details of the will were first reported by PageSix.com.
