Rapper Eve has been linked to a multi-million dollar money laundering investigation centred around her on/off boyfriend Teodorin Nguema.

Nguema, the son of Teodoro Obiang Nguema Mbasogo, the president of Equatorial Guinea, is under observation by authorities for a number of money transfers made between several U.S. bank accounts.

According to ABC News, Eve's name is mentioned in the massive U.S. Senate investigation, which has been under wraps for the past three years.

Nguema is alleged to have used lawyer friends, real estate agents and the rap star to set up shell companies in the States, through which he then wired cash to fund his lavish lifestyle, including the purchase of a mansion in Malibu, California.

The hip-hop star, full name Eve Jeffers, is named as the president of Sweet Pink, Inc., a firm set up in late 2005 and reportedly used by Obiang "to employ individuals at the home (Obiang) maintained before he purchased the Malibu Property and to handle payroll and other matters related to the employment of those individuals".

A representative for Eve had yet to respond to requests for a comment as WENN went to press.
