London , Apr 18 (ANI): There was a time when Amy Winehouse stood like a pillar by her hubbys side, but now the times have changed so much so that the singer snubbed Blake Fielder-Civil on his 26th birthday, fuelling speculations that the couples marriage is on the verge of collapsing.

The 24-year-old singer neither visited her jailed husband on his birthday on April 16, nor she sent a card in time.

From what her pals say, Amy is already living as a single woman but would not break up with Civil, at least not when he is behind the bars.

The Rehab singer is not quite regular when it comes to visiting Blake in Bentonville Prison, North London , where he is awaiting trial on assault and trial-fixing allegations.

Amy does everything she can not to visit. She forgets she is married half the time. There are a few men she is close to and Blake cant stand it, The Sun quoted a pal, as saying.

Amys dad is also speculating a split for his daughter, saying: It wouldnt surprise me if Amy and Blake had broken up. (ANI)
