A British heiress worth $1.4 billion has started divorce proceedings after reports surfaced that her husband, Dead Stays Alive frontman Tony Allen, had sex with Lindsay Lohan while staying at the Cirque Lodge rehab clinic.

The wife/heiress, Stephanie Allen, is the daughter of some packing god who makes McDonald’s boxes. (why couldn’t my dad think of that!) Stephanie filed 52 pages worth of Divorce complaints against Tony Allen this past week.

In the claim, Stephanie, who is filing for custody of the couple’s 8-month-old twins, states that her marriage is “irretrievably broken” and points to Tony’s “adultery” and “cruel treatment” as grounds for the split. The papers also accuse the musician of being “guilty of habitual drug addiction.”

The lawyers do not name Lohan in the actual complaint but they refer to Tony’s “conduct and relationship with another woman,” and Exhibit ‘A’, which is attached to the divorce papers, includes articles claiming Lohan, 21, started a relationship with Tony Allen while they were both being treated at the Utah rehab clinic.

Of course, Lohan’s rep tell US Weekly that this is not true at all. “It’s unfortunate Stephanie Allen is blaming the demise of her marriage on Lindsay,” the rep tells Us exclusively. “Stephanie needs to look at her marriage to determine the reason why things went wrong because it has nothing to do with Lindsay. Lindsay and Tony are friends and that’s all. They are supporting one another through a similar experience. This is a friendship based on trust and mutual support and nothing else.”

In the affidavit, Stephanie states: “My husband entered a drug rehabilitation centre in Utah…on or about July 11, 2007. After my husband’s return from said rehabilitation I was bombarded by telephone call alerting me to the fact that my husband’s conduct with another woman was on the internet and in gossip magazines.”

Tony has also denied the rumors, saying: “We’re great friends. We share a common affliction, and we just talk about life sometimes.”

However, another report claims that Tony was overheard in a bar bragging to friends about sleeping with the actress: “C’mon, it’s Lindsay Lohan. Hell, yes! Wouldn’t you?”
