Miranda’s Ex-Fiance Accuses ‘Arrogant’ Blake Of Cheating Too!

She’s a cheater and he’s a cheater. That’s what Miranda Lambert’s ex-fiancé is saying about the female singer and her ex, Blake Shelton.

Jeff Allen, who was engaged to Lambert, claims Shelton is the reason he and Lambert called it quits because the two country singers were having an alleged affair.

The cheating accusations surfaced on Twitter, beginning with Shelton posting a cryptic tweet on Thursday, April 26 after news broke that Lambert is dating a married man. 

It wasn’t long before Allen caught wind of the social media chatter and fired back, accusing Shelton of cheating on his ex-wife, Kaynette Williams.

“You know, I’ve always given you the benefit of the doubt and chalked it up to just being human, but you must be one arrogant SOB to pop off something like this, when I know damn good and well you were cheating on your wife and Miranda was cheating on me when you two started up,” Allen wrote on Twitter.

As RadarOnline.com readers know, Shelton was married to Williams from 2003-2006 before tying the knot with Lambert five years later. The two country stars divorced after four years of marriage.

Lambert is under fire this week for falling in love with married man. After suddenly breaking up with Anderson East after two years, she’s now shacking up with Turnpike Troubadours lead singer, Evan Felker, who is married. RadarOnline.com reported Felker’s wife, Staci Nelson, filed for divorce in February shortly after Felker and Lambert toured together.

Now, RadarOnline.com exclusively obtained bombshell photos of Lambert and her new man getting cozy in a restaurant. An eyewitness said the two locked lips "several times."
