Are things OK between Tamra Barney and Gretchen Rossi?

If a recent report in Radar Online is to be believed, things are less than copacetic between the Real Housewives of Orange County stars.

A source claims Gretchen wasn’t invited to Tamra’s wedding until the very last minute.

“Tamra and Gretchen have had a difficult relationship over the last few months and Tamra was insistent that Gretchen would not be there,” said the insider. “But at the eleventh hour, she [Tamra] changed her mind. It was a change of heart. She realized how important it was to have her there, despite all the petty drama.”

While Tamra Barney does seem closer with Vicki Gunvalson and Heather Dubrow (who were both bridesmaids in her wedding), she took to Twitter to slam the report, which had gotten picked up by the Christian Post.

Such a lie! @christianpost. It's a sin to lie,” wrote Tamra, linking to the article.

When one fan brought up how it was strange the Christian Post would be reporting on the wedding in the first place, Tamra replied, “I agree. Then to lie and say I didn't want Gretchen there until last minute. Lame.”

We wonder if Tamra’s wedding special, Tamra’s OC Wedding, will shed any light on this sticky situation!
