The Full Timeline: Marie-Anne Thiébaud’s Age, the Betrayal, and the Aftermath
By Alexander Ross
Lange announced his intention to leave Twain in the spring of 2008, citing vague incompatibility and emotional exhaustion. Distraught, Twain turned directly to Marie-Anne for support. During their private conversations, Thiébaud insisted that Twain was overreacting, actively counseling her that Lange was simply undergoing a midlife crisis and that no other woman was involved.
The deception collapsed because Frédéric Thiébaud refused to look away. Having noticed unexplained absences, credit card receipts, and evasive behaviors from his wife, Frédéric conducted his own investigation. He uncovered evidence of an ongoing romantic affair between Marie-Anne and Lange. Recognizing that Twain was being systematically gaslit in her own home, Frédéric drove to the singer's residence to deliver the truth directly.
Twain famously confronted Marie-Anne via telephone and written letters, begging for an explanation. Thiébaud denied everything before terminating contact, changing her phone numbers, and moving out of her family residence. Lange publicly dismissed the claims as "an absolute lie" through publicists, yet he immediately took up permanent residence with Marie-Anne.
