Dhaka: Arguments between star couple David and Victoria Beckham are reportedly threatening their marriage.

According to party-goers, the pair took out their frustrations on each other at Victoria’s Dover Street boutique this week, reports dailystar.co.uk.

They were celebrating the one-year anniversary of the 41-year-old designer’s store with friends where it was reported they were overheard having a bitter row.

A source told The Sun On Sunday: ‘Behind the scenes there appears to be a lot of tension. Victoria is very tired and stressed from working so hard whereas David has a much more relaxed attitude now he is retired.

‘They have had monumental four-letter rows as the tension between them snaps and they explode at each other. What keeps their bond strong is their children. They are both brilliant parents.’

The couple, who married on 4 July, 1999, have four children - Brooklyn, Romeo, Cruz, and Harper.
