Michelle Heaton has christened her baby son.

The Liberty X singer and her husband Hugh Hanley took their seven-week-old son Aaron Jay to the holy mass at Ballyroan Church in Dublin, Ireland, on Sunday (20.04.14).

The 34-year-old singer - who also christened her two-year-old daughter Faith at the same church in 2012 - took to Twitter yesterday to share an adorable snap of her bundle of joy in the car, wearing his long christening gown.

She accompanied the picture with: ''Getting AJ into his car seat with his christening gown on was challenging to say the least ! Lol xx (sic)''.

Earlier this month, the brunette beauty was left fearing for her baby's life after he contracted viral meningitis and was rushed to hospital for emergency care.

She said at the time: ''The last 24 hours has been the worst and scariest in my life.''

The tiny tot's conditioned improved and he was allowed to return home shortly afterwards, but Michelle won't know if he'll suffer long-term complications until he's a bit older.

She said: ''Our beautiful baby boy Aaron Jay Hanley is home now and we couldnt be happier. It has been hell, I'm not going lie, and only time will tell if Aaron has been physically or mentally effected with having had viral meningitis.

''But the chances are slight so we just pray he will be one of the lucky ones!''
