Lindsay Lohan's Samantha split confusion

Lindsay Lohan didn't realise she had split from girlfriend Samantha Ronson for a week.

The 'Mean Girls' actress - whose tumultuous romance with the 31-year-old DJ ended earlier this month - admits it took her several days to understand her relationship had broken down.

Asked if there is anything more difficult than playing out the end of a relationship in the public eye, Lindsay replied: "When you don't know you're breaking up. Really weird.

"I had no idea what was going on. I just hadn't seen her in like a week. She like, disappeared."

Despite her initial shock Lindsay claims she has now come to terms with the break-up, but refuses to rule out reuniting with Samantha.

She told US TV talk show host Ellen DeGeneres: "When people are together so much it gets really difficult and you forget who you are because you're more concerned about being with the other person, I think it's been really good for me. I thought it would be so much harder and it hasn't been. I've had great people surrounding me.

"I really care about Samantha and we'll see what happens. Maybe when we're fully in the right place. And I love her."

Lindsay also rubbished claims Samantha ended their affair because she cheated on the DJ, insisting she does not believe in infidelity.

The 22-year-old star is now planning to focus on her acting career and already has plans to star in a new movie.

She explained: "I feel like I want to get my career back in shape. There are some shows I'm producing that I'm really excited about. I'm doing a movie in October."

Report: Lohan and Ronson `taking a brief break'

Lindsay Lohan and Samantha Ronson have split — for now.

Lohan says that she and the 31-year-old Ronson, who announced they were a couple in September, are "taking a brief break so I can focus on myself."

Lohan, 22, made the comments to E! News Monday after a tumultuous weekend that saw the troubled pop star barred from a Ronson family party. The two have been dogged by rumors of arguments and breakups for months and are often photographed fighting.

Lindsay still with Sam: "We aren't broken up"

Lindsay Lohan is still very much part of a twosome. When asked whether there's any truth to the breakup rumors dogging her and Samantha Ronson these days, the 22-year-old actress answered unequivocally.

"Those rumors aren't true. We aren't broken up," Lohan told a source Wednesday, speaking from a penthouse suite at the Chateau Marmont in West Hollywood, where she was doing promotional work for her new spray-on self-tanner, Sevin Nyne.

Hanging out with Lohan today were sister Ali and Mom Dina, who flew in from New York earlier this week to spend time with her eldest daughter.

"They've been spending time with their families and working," a source says. "It's normal and healthy to do that. That doesn't mean they broke up!"

We're told that Ronson, who was in Florida for a gig Tuesday, is back in L.A. and was hanging out today with her fashion designer sister Charlotte, in town for work.

"They need to stop saying we're fighting," she said. "People telling lies about me to her and all this garbage. I'm really a good person and I have a good heart and just want to work. The only reason I go to clubs is to hear Samantha spin or be normal."
