Jessica Biel now has "the power" in her relationship with Justin Timberlake.

The stunning actress rekindled her romance with the 'In Time' star earlier this year after a brief split and now friends say she has the upper hand and he would even consider marriage if that's what she wants.

One told Us Weekly magazine: "Justin thinks marriage would hurt his career, but if Jessica threatened to leave, he'd do it. She now has the power in the relationship."

However, Justin, 30, may not to have to worry about getting married just yet as Jessica, 29, recently revealed she is in no hurry to settle down.

When asked if she would like to get married and have children, the brunette beauty replied: "Sure, of course. And, yeah, I think probably at some point it would be something I'm interested in. But I don't feel pressured.

"I was never one of those girls who dreamt of my wedding and my Prince Charming. To p**s off my mom, I used to say, 'I'm never having kids, and I'm going to be a fabulously rich old maid living in a house with cute butlers and dogs.' "
