Madonna's latest album is set to have the biggest second week sales drop in US chart history.

The 53-year-old singer's new record 'MDNA' debuted at the top of the US album charts last week after achieving sales of 359,000.

However, according to Forbes, in its second week of release, sales fell to approximately 46,000, making it a record-breaking 88 per cent fewer copies sold.

Reports say Madonna's first-week sales were inflated by CDs that were bundled with the purchase of concert tickets for her upcoming tour.

According to the Hollywood Reporter, 185,000 copies of 'MDNA' were sold as part of the ticket package deal, meaning that only 179,000 were individual album sales. Without these ticket package sales, 'MDNA' would have placed at Number two on the charts behind Lionel Richie's 'Tuskegee', which achieved 199,000 copies that week.

Forbes' Roger Friedman believes Lionel was robbed of the number one position.

He said: ''That promotion artificially inflated Madonna's numbers, putting her first before 'Lionel Richie' and his 'Tuskegee' album.

''I do think that all the people involved in the Madonna ticket-CD deal should apologise to Richie for denying him his rightful place at number one.''
