Jennifer Garner & Ben Affleck have hit back at reports that their marriage is in crisis.

Rumours that the low-key pair - previously thought to have one of Hollywood's more solid relationships - have split surfaced after they were photographed spending time with daughter Violet separately.

But a spokesperson for Garner has called them "one hundred per cent completely fabricated".

The Juno star's rep adds: "There is not one ounce of truth to it."

Affleck and Garner married in 2005.
