The Pitch Perfect star had reportedly been spotted enjoying a recent low-key date in Las Vegas with Allen, the younger brother of British singer Lily, sparking speculation about a new star romance. But Kendrick has brushed off the rumours.
Addressing a Gawker.com article about an alleged liaison on Twitter.com on Wednesday (13Aug14), she wrote, "@Gawker Ahh, this has been hilarious and all but, nope. My apologies to Mr. Allen, who must be equally confused."
Kendrick has been single since splitting from her boyfriend of four years, director Edgar Wright, in early 2013.
Allen, who portrays Theon Greyjoy on the hit fantasy series, ended his on/off relationship with actress Jaime Winstone last month (Jul14).
