A wife discovered her cheating husband's secret second family after he was tagged on Facebook doing the Ice Bucket Challenge with his new spouse, the Daily Mail reports.

Andrew O'Clee, 36, was married to Michelle for three years before he forged a decree absolute and tied the knot with second wife Philippa - while he and his first wife were trying for a baby.

In an extraordinary twist, he then lied about entering the Witness Protection Programme and said he had to live in a safe house so he could spend more time with his new family.

But the father-of-one was caught out in the elaborate lie after four years when a video of his Ice Bucket Challenge appeared on Facebook captioned 'uncle Andrew and auntie Philippa' - which was seen by Michelle.

She reported him to police and O'Clee has been jailed for eight months at Chichester Crown Court for bigamy.

Michelle even revealed that he showed up briefly five hours late at the birth of their child - cut the umbilical cord and said he had to leave with police.

She said O'Clee told her he was involved in a fraud case and had to enter the Witness Protection Program which would keep him away from home for long periods.  

The court heard he forged a decree absolute to show his family so his mother and brother believed he had divorced Michelle and they happily attended his second wedding.

Judge Christopher Parker QC said: 'You began to develop a complicated and absurd lie.

'All of which was a complete nonsense but it enabled you to lead a double life.

'The question is, why on earth would you do it? You are a shameless liar, happy to have as much comfort wherever you could find it.

'Bigamy is an offence against the institution of marriage, an institution founded on complete trust. This was simply a selfish act.'

O'Clee met Michelle in 2000 and they married in 2008, and began his affair with his second wife in 2011.
