(BANG) -Justin Timberlake has banned Jessica Biel from mentioning "marriage". The on/off couple - who have been romantically involved for just over two-and-a-half years - have reportedly fully committed to each other again under the condition Jessica stops putting pressure on the 'SexyBack' singer to propose to her.

A source told OK! magazine: "Justin is just not interested in getting married right now."

Apparently, the pop heartthrob cooled the romance down a few months ago when the actress asked when they would get married.

It is claimed Justin is not ready to tie the knot because he has witnessed the breakdown of so many unions, including his parents Lynn Harless and Randall Timberlake who split in 1985.

But Jessica, 27, has promised Justin, 28, she will wait patiently for him.

The source added: "Jessica knows that if she and Justin are ever going to have a future, she has to be willing to be patient."
