Cristina Gibson of E! reports Lindsay Lohan was dining with her mother Dina on Sunday night at Cecconi’s in West Hollywood when ex-girlfriend Samantha Ronson was also eating at restaurant with a group of guys. The DJ stopped by LiLo’s table to say hello before leaving alone.

A Lindsay Lohan friend tells People magazine that the 22-year-old is “heartbroken” following her Samantha Ronson breakup. “Sam and Lindsay are speaking,” the source said. “But Sam has begged Lindsay to get help. Lindsay, despite appearances, is insecure and has relied on Samantha and their relationship to build her up.”

A friend added that Lindsay’s kid sister Ali “has been there for her and coaching her through [the split].”

Lindsay Lohan had reportedly complained about ex-girlfriend Samantha Ronson cheating on her the night of the big blow-up, and now Bill Zwecker of the Chicago Sun-Times reports that the DJ was “clearly with another woman — somewhat of a Lindsay look-alike, but with very dark hair” at the Chateau Marmont that fateful evening. A Ronson friend identified the woman as “Cindy”.

A source close to Samantha Ronson tells People magazine that the DJ is not interested in getting a restraining order against ex-girlfriend Lindsay Lohan following their drama at Ronson’s party at Bar Marmont over the weekend. “Sam does not want a restraining order against Lindsay Lohan. Sam had nothing to do with the restraining order against Lindsay that the police are talking about.” The mag adds that Lohan and Ronson “are totally communicating” despite their recent issues.

OK! magazine hears that on Monday, Samantha Ronson’s mother, Ann Dexter-Jones, and sister, fashion designer Charlotte Ronson, were at the Beverly Hills Police Department to look into filing a restraining order against Lindsay Lohan because the DJ wants to “send a message” to the troubled 22-year-old.

Charlotte allegedly complained to the clerk, “She does these things to get attention. She was trying to get into my party this weekend. We had to tell security to keep her out. Then she booked a room at the Chateau Marmont. Her room was right below… She also followed our brother Mark around.”

And Ann made even more serious allegations. Check out the details here.

UsMagazine.com has more details on Samantha Ronson’s party for her fashion-designer sister Charlotte at West Hollywood’s Bar Marmont over the weekend, where the DJ blocked on/off girlfriend Lindsay Lohan from attending.

“[Sam] told security to look out for Lindsay and block her from getting in,” a source told the magazine. “Lindsay, of course…booked a room at [the hotel] Chateau and fully intended to crash the party and make a scene.” The tipster added that the decision was made to prevent Lindsay from “causing a scene and ruining Charlotte’s night”.

As for whether this latest spat will mark the end of Sam and Lindsay’s troubled relationship, the source said, “This time, Sam means it.”

Samantha Ronson was doing DJ duty at a party for her fashion designer sister, Charlotte Ronson’s I Heart Ronson clothing line for JCPenney on Friday night, but OK! magazine reports Sam’s on/off girlfriend Lindsay Lohan was barred from attending.

Doormen were told strictly not to let LiLo in the building, and when she showed up around midnight, an onlooker says Lindsay was “restrained from coming in by five security guards.” Those who were allowed to attend included Nicole Richie, Molly Sims, Sting, Jewel, and Paris Hilton.
