It may well be over romantically between former lovers Samantha Ronson and Lindsay Lohan — or at least for now — but that doesn’t mean that emotions, and tempers, aren’t still running high.

They are — so high in fact that RadarOnline.com has exclusively learned the twosome got into a bitter, heated fight Wednesday night, which culminated in Lohan throwing a drink in Ronson’s face!

Lindsay Lohan can be seen on ‘The Insider’ this Thursday discussing her latest diagnosis: secret celebrity hoarder.

“It’s kind of a sore subject,” Lindsay tells Niecy Nash in the teaser. Then she faces a room filled with shoes and clothes and dramatically intones, “I just need to get rid of this stuff.” Supposedly her hoarding is a coping mechanism for the hurt caused by her father, shown in the opening montage.

‘The Insider’ routinely pays its subjects for interviews, but Lindsay is no stranger to collecting paychecks from dubious sources. Next week she will accompany a 77-year-old Austrian billionaire to the Vienna Opera Ball for a reported $150,000 payday.
