Reese Witherspoon's boyfriend has reportedly been shopping for an engagement ring.

Jim Toth - who has been dating the 'Walk The Line' actress for almost eight months - has allegedly been spotted in several Hollywood stores looking for the perfect ring to propose to the beauty with.

A source said: "Reese wasn't with him, because he wants it to be a surprise. But he knows her style. The ring will be classic and beautiful, just like Reese herself."

The pal went on to add that Reese - who has two children, Ava, 10, and six-year-old Deacon with former husband Ryan Phillippe - is more serious about Jim than she was about 'Brokeback Mountain' star Jake Gyllenhaal, who she dated for two years prior to embarking on a romance with the Hollywood agent.

The insider added to America's InTouch weekly magazine: "She never considered marrying Jake. She loved him, but wasn't passionate about him. Jim is her ultimate guy."

However, a friend of 34-year-old Reese - who married Ryan in 1999, divorcing seven years later - recently advised she is not ready to fully commit to the relationship until she is sure things will last.

They said: "Reese got married too young the first time, and she never wants to go through another divorce again. She wants to take things very slowly."
