LeAnn Rimes sends arch rival Brandi Glanville FLOWERS on Mother's Day...who 'thanks' her with Twitter jibe

She and her husband's ex Brandi Glanville have been embroiled in a public and bitter feud.
But it appears LeAnn Rimes' efforts at burying the hatchet have not quite gone as planned.
The 30-year-old, who calls herself a 'bonus mom' to husband Eddie Cibrian and Brandi's two sons Mason, nine, and Jake, six, sent her longstanding love rival flowers on Mother's Day, only to be slammed by the reality star via Twitter.

Brandi tweeted on Monday that she had thanked LeAnn via Twitter for the flowers, but couldn't resist a jibe at the singer.
'I thanked @leannrimes on twitter4 my flowers.Our relationship is that we still dont even say hi at baseball.I dont have her number-thats it,' wrote the Real Housewives Of Beverly Hills' star.
When a follower of LeAnn asked her about the gift, the Grammy winner wrote that the tweet 'was actually the first acknowledgement of my gesture I was made aware of.'
'I didn’t see anything else sent to me,' the Grammy-winner wrote. 'It wasn’t for the "thank you." It was to just simply say Happy Mother’s Day.'

LeAnn and Eddie treated their mothers with a lunch in Malibu, California on Sunday, while Brandi spent her Mother's Day lunch with her two boys alongside Eddie's ex mistress Scheana Marie, who slept with him while he was still married to the reality star.
The pair bumped into each other Lisa Vanderpump's restaurant Villa Blanca in Beverly Hills, but Brandi was quick to clarify that Scheana's presence didn't affect her.
'I went to @PandoraVT mothers day brunch on a Monday while my boys were N school I didnt know or did I care that Eddies ex mistress was there'.

LeAnn, meanwhile, was clearly in the Mother's Day spirit, sharing her sentiment about taking on the new role as a 'bonus mom.'
Sunday afternoon she retweeted a post by StepMom Magazine, which read: 'Don't allow anyone else (including Hallmark) to define how you feel about yourself today. #TwitterStepmoms.'
'It's not easy being a step-parent, taking on a mother or father role in your new blended family and household,' she wrote in a blog post.

Despite all of LeAnn's Twitter activity over the past weekend, questions have been raised about the number of followers she actually has, along with accusations that she has been buying followers and using robot followers to increase her numbers.
According to RadarOnline.com, the singer's followers increased by 100,000 last month, but most were gained in a two day span.
One telling sign was that the vast majority of LeAnn's followers had a non-descript and generic profile photo of an egg and had no followers themselves.
'Tell tale sign of someone buying followers is a big spike followed by a big unfollowing. #LeannRimes has dropped 10,000 after buying spree!' user @lindami77281989 wrote on Sunday.
Also noticing was @IWiveClub tweeted, 'wauw, six retweets…where are all these Leann Rimes followers fans? Sorry I forgot, most don’t exist.'
