Blake responds to split rumours with playful Father’s Day message

With work keeping them apart, and a baby daughter to look after, it's no wonder that Blake Lively and Ryan Reynold's three-year marriage has reportedly been under a lot of strain in recent months.

But after maintaining a dignified silence in the face of continued split rumours, Blake today seemed to tell the world that she and her husband are as solid as ever.

Marking Ryan's very first Father's Day – James was born in December – Ms Lively posted a humorous message to her Instagram account.

With an accompanying image of a strapping-looking Mr Reynolds cradling his daughter in a harness, the 27-year-old actress wrote: "Happy Fathers Day!!! … @vancityreynolds.

"Since the day our baby was born, I've felt so strongly in my heart that you were most likely the father."

However, she countered the light-heartedness of the online memo with a touching hastag: #ILoveYouSoMuchItsSilly

The pair, who met on the set of Green Lantern in early 2010 and began dating in October 2011, have so far not released any pictures of their daughter.

Still, in Blake's shot from today, James's tiny sock-clad feet can be sticking out from the bottom of her harness. 

Last month, Ryan, 38, also shared on Instagram a snap of his hand and his daughter's intertwined. 

Both actors have spoken gushingly of their love of parenthood, though on a recent airing of the Tonight Show, Blake jokingly told host Jimmy Fallon that she does "everything". "He does nothing!" she added.
