BP chairman had an affair as oil leaked

British Petroleum boss Carl-Henric Svanberg isn't feeling the heat just because of the massive oil spill threatening the Gulf of Mexico -- he's reportedly also the bad guy behind the breakup of another couple's marriage.

In legal documents obtained by The National Enquirer, Louise Julian and her hubby of 18 years filed for divorce on May 24 after Svanberg had been wooing the 51-year-old mother of three since last year.

The couple originally separated in July 2009 due to "serious and irreconcilable differences."

The National Enquirer reported the bombshell love triangle in this week's edition. Svanberg even vacationed with Julian on his private luxury yacht in Thailand just days after BP's Deepwater oil rig exploded on April 20, killing 11 people and causing a massive disaster off the coast of Louisiana, the tabloid reported.

The 58-year-old Svanberg, who hails from Sweden, divorced his wife of 26 years in November 2009. They have three children.

According to the court papers, Louise Julian will keep the couple's home in Brookline, Mass, in addition to two homes in Stockholm. Her husband, Gary Julian, will keep the family's condo in Colorado.

Two weeks ago, Svanberg apologised after calling those affected by the oil spill as "the small people."

"I spoke clumsily this afternoon, and for that, I am very sorry," he said following a meeting with US President Barack Obama.

"What I was trying to say -- that BP understands how deeply this affects the lives of people who live along the Gulf and depend on it for their livelihood -- will best be conveyed not by any words but by the work we do to put things right for the families and businesses who've been hurt."
