Lindsay Lohan's lady friend DJ Samantha Ronson raised concerns over her health after she paid a visit to a Los Angeles hospital yesterday after news surfaced she's been battling depression.

The 31-year-old DJ and girlfriend Lindsay Lohan were spotted making their way into Cedars-Sinai Medical Center in L.A. on Sunday, shortly after a report in Life and Style magazine claimed friends of the celebrity DJ were worried because she is suffering from exhaustion and depression.

"She's been suffering from depression and from lack of food and sleep," an insider told the mag. "Gal pal Lindsay Lohan has been helping her through this as she has been through this herself two years ago."

Hollywood-based Ronson was seen laying in the backseat of her car by Lindsay's side before she was escorted into the hospital in a wheelchair. While calls to the hospital and the actress' rep were left unanswered, Ronson won't be spending the holidays in the hospital. She is expected to be released from the facility any moment now.

Ronson's friends said they received "frantic" phone calls from her a day prior to the hospital visit and that she was confused, as she "knew she had done something wrong."

Since dating Lindsay Lohan, the spinner slowly increased her fee, from around $1,500 to as much as $25,000, netting Ronson close to $3 million over the last year. The reason behind the increase is Lindsay's presence to the gigs. Although she doesn't contractually agree to bring her girlfriend along, "promoters, owners and publicists all know that if you book Sam, there’s a high likelihood Lindsay will also show," an insider close to the couple told Daily News.

However, a representative for Ronson denied that she was using her relationship with Lohan for financial gain, and that she's perfectly capable of making money on her own.
