Heather Dubrow and her husband, Dr. Terry Dubrow of E!'s Botched, are being accused of ruining a weekend party.

According to a new report, former Real Housewives of Orange County star Gretchen Rossi threw a party over the weekend in honor of the launch of her new handbag collection and during the after-party, the Dubrows reportedly caused tension with their co-stars.

“After Gretchen’s show, a whole group of people went to eat sushi and celebrate. When they arrived at the restaurant they were all shocked because their table of ten people was right next to where Heather and Terry were seated,” a source told Radar Online on Thursday.

“Neither Heather nor Terry got up to go and say hi to any of them,” the source explained. "It was beyond shady."

Although Rossi's party was reportedly attended by several Real Housewives of Orange County season 11 cast members, Dubrow and her husband went out of their way to avoid them.

“When Heather and Terry were done eating they went way out of their way to completely avoid the group. They were right next to them near the entrance, but chose to sneak out the back door without saying a word to anyone,” the source said.
