Adrienne Maloof Ignores Brandi Glanville Hours After Quitting The Real Housewives of Beverly Hills

USMagazine, Tuesday, March 5, 2013, 1:00pm (PST)

Tension was in the air when Adrienne Maloof and Brandi Glanville crossed paths on Monday, March 4. Hours after the multimillionaire announced she would be leaving The Real Housewives of Beverly Hills -- Maloof had skipped the reunion taping March 1 -- the bitter enemies avoided each other at the Polo Lounge in Beverly Hills.

"Brandi was clearly uncomfortable but laughing," a source tells Us Weekly of the 40-year-old Drinking & Tweeting author, who was catching up with two male pals. "They didn't acknowledge each other at all."

Maloof, meanwhile, "was having fun with her girlfriend and talked to Al Pacino. She and Al exchanged business cards." The single mom -- dating Sean Stewart, 32 -- went to the bathroom with a female friend around 10:15 p.m.

"Brandi literally followed them into the bathroom," the source reveals. "They ignored her and walked out. It was so creepy."

A source close to Glanville confirms the Bravo stars "didn't even look each other in the eye" and made an effort to avoid one another. "They were in the bathroom together at one point and didn't even say a word to each other."

The women famously feuded during the Bravo reality show's third season, due in large part to Glanville revealing that Maloof's 6-year-old twins, Christian and Colin, were born via surrogate. (Paul Nassif and his then-wife sent Glanville a letter threatening legal action.)

Maloof, 51, announced her exit from The Real Housewives of Beverly Hills via her official website March 4. "The show served as a wonderful platform for all the amazing projects that I have in the works," she wrote. "I am forever grateful to my fans, thank you for your support, and stay tuned!"
