Tamra Barney accused Gretchen Rossi of being unfaithful to her dying fiance.

Last night marked the first installment of the three-part reunion of The Real Housewives of Orange County Season 8, and the ladies kicked it off with a bang.

Of all the drama that went down, nothing was more explosive than Tamra Barney (once again) accusing Gretchen Rossi of having an affair when her ex-fiancé Jeff was dying. What's most shocking is that Tamra pulled out photographic evidence to prove it.

Here's what went down: Tamra revealed in the 100th episode special that she spotted Gretchen with another man while her fiance was in the hospital. And on last night's Reunion Special, she brought her proof, which purports to show Gretchen allegedly kissing another man. Gretchen vehemently denied she cheated on her husband and, despite Tamra's proof, she stuck to her guns.
