Liam Payne was forced to call in plumbers to deal with a rotten eggs smell lingering around his house.
The One Direction star – whose girlfriend Cheryl is expecting their first child together – is hoping to have the problem fixed this month by bringing in some experts to sort out the stench around his £5 million house in Surrey, south east England.
A source said: "The smell reeked of rotten eggs and left a taste in your mouth when you walk past."
Liam’s neighbors are said to be hoping his workers will be able to quell the "thoroughly unpleasant" stink before Christmas.
The source added to The Sun newspaper: "Plumbers were trying to get to the root of the problem last week and neighbors were hoping it could be done quick.
"It was thoroughly unpleasant."
Pregnant Cheryl, 33, may also be hoping the eggy pong goes as the pair prepare to spend their first Christmas together as a couple.
Liam, 23, recently admitted he is the "happiest" he’s ever been in life.
During a Twitter Q&A, one fan asked him if he is happy and he replied: "the happiest i could be (sic)"
While Liam and Cheryl are yet to confirm their baby news, their relationship is said to be so serious he is considering popping the question in the delivery room after being inspired by Kimberley Walsh’s partner Justin Scott.
A source recently said: "Liam got the idea to propose straight after the birth after finding out that Justin popped the question after the delivery of their first child. It’s given Liam so many ideas. There will definitely be wedding bells sooner than we expected."
