Jennifer Garner and Ben Affleck are planning to renew their vows, it has been reported.

While some couples experience the seven year itch', Jennifer and Ben plan to walk down the aisle again on their seventh anniversary this June.

The couple tied the knot in 2005 in a private ceremony on the Turks and Caicos Islands.

A friend told In Touch that the birth of their third child, a son called Samuel, in February has put the spark back into their marriage.

They have now decided to pay tribute to their love with a ceremony attended by close friends and family.

"They want to renew their vows with their kids," a friend said. "It'll be great.

"Like any couple, they've had their ups and downs. But they are crazy in love with each other."

Jennifer and Ben also have two daughters six-year-old Violet and Seraphina, three.

Jennifer's Alias co-star Victor Garber officiated at their first wedding ceremony and is tipped to be the man in charge the second time around.
