LOS ANGELES, Calif. --

Reese Witherspoon may need to buy another toothbrush.

Boyfriend Jake Gyllenhaal has moved into Witherspoon’s $5 million Los Angeles home, according to Us Weekly.

“Marriage is definitely what they are working toward,” a source told Us Weekly.

Meanwhile, a friend of Witherspoon said the celebrity couple, who has been together for one year, has been relatively inseparable.

“They literally don’t want to spend any time away from each other,” the friend said.

Gyllenhaal is reportedly helping raise Reese’s two children, Ava, 8, and Deacon, 4, from her marriage with actor Ryan Phillippe.

The Oscar-winning “Walk the Line” actress finalized her divorce from Phillippe earlier this month.
