Robert Pattinson never dated Riley Keough, according to her mother Lisa Marie Presley.
The actor was linked to the rising actress and model earlier this year following his split from Kristen Stewart, but her mum insists she never engaged in a relationship with the hunk and says Riley and Kristen - who co-starred in 2010's 'The Runaways' - are close pals.
Appearing on US talk show 'Watch What Happens Live' on Thursday (17.10.13), she said: "I don't want to say who she's with or not, I will say who she's not with and that is a complete lie, and the silliest thing I've ever heard, is that she was with Robert Pattinson... because her and Kristen Stewart are like best friends. So that was the craziest rumour that I will put to bed."
While Riley, 24, may not have dated Robert, 27, she was recently rumoured to have rekindled her romance with another actor - 'Magic Mike' hunk Alex Pettyfer.
The couple began dating in October 2011 and got engaged six months later, but ended their romance some time in 2012.
Riley and Alex, 23, were spotted getting cosy at a premiere party for his new movie 'The Butler' in Los Angeles over the summer, leading to speculation they are back together.
