Tamra Barney is not very happy with Gretchen Rossi after this week’s episode of Real Housewives of Orange County! After mending fences last season and putting their feud behind them, it seems that Gretchen is doing things that Tamra just is not going to let slide.

Back in February, Tamra told AllAboutTRH exclusively that some stuff happened during filming that reminded her of why she was not friends with Gretchen in the past, and it looks like we are finally at that point in the season. Tamra reveals in her Bravo blog:

Gretchen is claiming that I told her I did not want Alexis at my dress shopping day. Well there is a little truth to that, let me explain.

When I told Gretchen that Alexis was invited she instantly was pissed and said she didn’t want to go. She pleaded her case to me and I listened. I thought, “You know what Gretchen is right and Alexis should not be at my special day.” I told her that I would tell Alexis that she could not go so I could have Her there.

After sitting on it for a few days I started thinking. Wait, this is MY day NOT Gretchen’s and why am I letting her tell me who I could invite?

After all, I had made up with Alexis and was trying to move forward. Heather had made up with Alexis too, so if there was going to be any fighting it would be between Gretchen and Alexis — and Gretchen had told me she didn’t want any of that. Gretchen had no problem being around Alexis at the salsa party and even hugged Alexis goodbye. This was so confusing to me.

So after Gretchen realized I was not going to rescind the offer to Alexis she sent me a text (Plan 2) telling me that she was offered a role in the new Reba McEntire show. She called it Big Country (she didn’t even have the correct name) and would be filming all day Friday, the day we were at Mark Zinino’s store.

I told her, “Congrats. That’s wonderful and please don’t worry about me. The experience of being on your first sitcom was more important.” Basically I called her bluff without even knowing it.

Fast forward to the day before dress shopping, I get a text message from Gretchen that she is turning down the role to spend the day with me looking for a dress (which is ironic because she did not spend one second trying to help me find a dress. She was off to the side by herself). Regardless, at the time I thought she did a sweet thing.

When we picked Gretchen up I was a little shocked to see her in a bright red jacket with no dress on underneath (it was winter and raining) and with an engagement ring on her left ring finger. It screamed “everyone look at me.”

I have not seen her wear that ring in four years and she choose to wear it on the day I was looking at wedding dresses? Come on! I ignored it and tried to stay positive but Vicki on the other hand was thinking the same thing as me.

On to the big expose of Gretchen’s lie during lunch. Heather told the group that Gretchen had not been offered any role on Malibu Country, she was just part of a casting call for many reality TV stars. That’s when Tamra learned Gretchen had been lying! Tamra reflects:

Heather had told me she had some news to tell me at lunch. After she told me it all made sense. Gretchen lied to me! Gretchen had been telling Heather the same story about how she got this role and she would be filming on Friday but decided to give it up just to be with me. Heather being the professional did not tell G she had been cast on that show and that she knew there was no offer given to Gretchen — only a casting call that many reality stars were called for including Alexis. That was quickly abolished before interviews ever happened.

Honestly it breaks my heart that she would lie to me after I had just opened up to her. But what hurt me even worse is her text to me two days after dress shopping.

Basically, she texted me to tell me what a great friend she was to give up her first role on a sitcom to spend that important day with me.

I didn’t have the heart to tell her I knew she was lying. What was her point? Did she want to make me feel bad? Like I owed her something? I needed time to process everything and deal with it another day.

To this day I don’t understand her motive for not wanting to go dress shopping with us. What was the real reason why she didn’t want to go? You could tell my by her body language that she did not want to be there

Was it about Alexis or because it wasn’t about Gretchen?

Who to believe?! There is one thing that is true though – the reunion will not be pretty for Gretchen. Alexis, Tamra, Heather and Vicki will not be happy with her. And if Lydia is still upset about Slade’s comment, then Gretchen is basically on her own. Do you think Gretchen is a liar?
