The R&B star made a surprise appearance at the top of the show, when she performed her hit Formation, but the singer did not return to the stage to collect her awards, leaving her mother to explain that Beyonce had dashed off to catch a plane to London for a concert in the U.K. on Tuesday night (28Jun16).

Fans refused to believe Beyonce had left the building and suggested Tina was lying about her daughter's whereabouts.

Knowles has now responded to the haters in a statement, in which she admits she blundered about the exact date of Beyonce's gig, telling the BET audience the concert was scheduled for Monday night.

"I asked why did she have to leave early and was told by a member of her staff that 'she had to get back in time for her concert' and that she actually should have been there 2 days before," Tina writes. "I want to point out that there is a nine hour time difference and it is an eleven to 12 hour Flight that equates to 19 - 20 hrs (hours) to get there! I then want to ask what would be the point of lying to the public...

"Any one with good sence (sic) could see that! I am hurt and disappointed because I know what kind of work, sacrifice, and personal Money it took for her to do this show and support the Bet Award show and to give her fans that did not get to attend the concert a piece of her show. (Even though it means she has one day to rehearse herself and dancers after being off for a month) That was really important to to her.

"Although everyone told her this is going to take a toll on your tour because you will only have one day to rehearse and you and the dancers will have been off for a month. You will be exhausted because you get to the states on Thursday rehearse for Bet fly to Mexico to be with your Sister for her Birthday on Friday get back to La on Sunday and start rehearsals at Bet At 7 am. (Who else would get three hours of sleep like that?) Book a huge private plane to carry your dancers and creative staff and choreographers road Managers and pay for it out of your own pocket. Who does that?"

"Please understand that I absolutely am not doing this for anyone but myself!" Tina adds. "I know I owe no explanation to anyone but I am tired of people writing my story. So I chose to tell my own!"
