Bitter feud reignited between these two reality stars

Former TOWIE stars Sam Faiers and Lucy Mecklenburgh have always had a few, shall we say, issues with one another and now it looks like things are beginning to escalate.

The pair, who were once good friends, are no strangers to drama having gotten into numerous spats over fellow TOWIE cast member Mark Wright.

Before meeting former Coronation Street actress Michelle Keegan, Mark briefly dated both Lucy and Sam – that's a goldmine for drama right there!

This latest development is more to do with work and less to do with men, though. Both ladies have used their passion for fitness to their advantage in recent months, with Sam starting her own health and training website at the beginning of this month, and Lucy launching her own book and fitness company, Results With Lucy, last year.

It seems Lucy isn't too happy with Sam jumping on the fitness bandwagon, though, as she has now blocked Sam's official account on Twitter. Ouch.

"Sam’s and Lucy’s Twitter handles were both tagged in a tweet by a follower, but when Sam’s team, who run the account with Sam, went to reply, they found that Results With Lucy had actually blocked them," said a source close to the pair.

A simple mistake – or something more significant? We hope it's the former, but with these two you just never know!
