On a recent episode of Watch What Happens Live, former Real Housewives of New York star Heather Thomson wasted no time telling host Andy Cohen how she really felt about her fellow ex-RHONY castmates (especially Sonja Morgan).

Heather was a regular on RHONY seasons 5, 6, and  7. She's known for her famous line, "Holla." Two weeks ago, she appeared on WWHL along with sportscaster and former Dancing With The Stars host, Erin Andrews.

While most fans have been saying they like Sonja Morgan's new look, Heather told Andy, "I liked the old face". This response came after he asked, "What did you guys think of Sonja's new face?" Heather also threw Sonja under the bus on Bravo's WWHL, after being asked who the worst RHONY tipper was. "Sonja is the worst tipper and Ramona is not so great either", she remarked. She added about Sonja, "She'll even get up and leave without paying for the meal." Heather also added that Sonja and Dorinda are the least fun to be around when they're drunk. She said LuAnn was the most fun Housewife when inebriated.

Heather of RHONY fame did (finally) have one nice thing to say about Sonja. She paid a compliment after Andy Cohen asked her, "What do you think about Sonja's line for Century 21?" Heather responded with, "She's certainly taken a lot of crap by you and everyone else about product that fail to launch & she finally did." She said passive-aggressively, "Failure to launch can only be superceded by launching. So kudos to her for holding in there, putting the nose to the grindstone and finally getting it to launch. So I'm very happy for her & excited for her."

While some of Heather's comments were a bit rough around the edges, Erin Andrews appeared quite humble. Andy asked Erin what she thought of DWTS host Tyra Banks's comments about her new Dancing with the Stars job (Tyra said, "It will be a challenge to step into her shoes." ) Erin humbly said. "I think Tom's (Tom Bergeron)  shoes are a little harder to fill. He's the guy. He was the quarterback of the ballroom. That was nice of her, but he's the man on that show." Luckily, Erin (who viewers) found out is a Housewives fan, has her other night job to fall back on, and said, "We need sports. We need something to look forward to. I love having Housewives on every night, but I need my little tomboy action to watch on TV." Erin also discussed her new female game day apparel line.

Heather recently launched her own podcast. It's called In My Head with Heather Thomson. Her first guest will be Beyonce Knowles' mom, Tina Knowles. Of the show, Heather said, "After leaving the show (RHONY) it was so important for me to have another platform for a connection with people, ideas & what's in my head. I want to dig deeper." Heather also mentioned that Andy will be a guest on her podcast.  She said of her new podcast, "We show you our heart."

Let's hope the former RHONY star reexamines what might be hurtful to Sonja's heart and adjusts accordingly.
