Reese Witherspoon and Jake Gyllenhaal Want Pet Dog at Their Wedding

Hollywood couple Reese Witherspoon and Jake Gyllenhaal want their dog to be the ring bearer at their wedding.

The Legally Blonde actress and the Brokeback Mountain star -- who began dating after they met on the set of 'Rendition' last year -- want Jake's beloved German Shepherd Atticus to have the important role when they tie the knot.

Although Atticus originally belonged to Jake and his ex-girlfriend Kirsten Dunst, the pooch has now moved in with Reese and her two children, eight-year-old Ava and four-year-old Deacon, from her marriage to Ryan Phillippe.

A source reveals, "Atticus now lives with Reese full-time. He is great with her kids and makes her feel safe when Jake is away.

"It was totally Reese's idea to give Atticus a role in the wedding. Jake has fallen into the role of stepdad to her kids, so it is only fitting that Reese has more or less adopted Atticus as her own too!"

Jake, 27, recently moved into Reese's $5 million Los Angeles home, fueling rumors the couple are planning to wed soon.

A source said: "Marriage is definitely what they are working toward. They literally don't want to spend any time away from each other."
