The Quartet star is said to have reached out to Andy on after being introduced by the bassist's brother, who is pals with Sheridan. They reportedly enjoyed a series of dates over the past few weeks, but Sheridan has made it clear any romantic relationship they may have had is now over.

She took to on Monday (05Oct15) and revealed she is excited to throw herself into her work in a new stage revival of Funny Girl in London later this year (15).

"Single!!!!," she tweeted. "bring on funny girl, who's coming???!! Can't wait xxx."

When one follower questioned her "single" status, she replied, "I sure am... bye boys!!"

Sheridan, 34, has since deleted the tweets, although one message she posted over the weekend (03-04Oct15) remains. It reads: "I am so grateful for all the support & love from my genuine friends, can't tell you what it means. Thank you for always having my back".

Andy has yet to comment on the split rumours.
