Journalist Ian Halperin, from celebrity blog Ian Undercover, broke the unconfirmed reports early this week.

According to the website, Lohan has slept with a number of men following her break up from DJ girlfriend Samantha Ronson, and reportedly doesn't know who the father is.

'I swear she's carrying,' a source told Halperin.

'She's going through big emotional turmoil. She's not sure if she'll have it or go through with an abortion that she booked to have in the next few days.

'Saddest part is she has no idea who the father is. She must have slept with more than two dozen men in the past couple of months.' -- AP
