The Legally Blonde star began dating Jim Toth only last month but the Hollywood agent is already planning to pop the question, reported InTouch Weekly.
"He is not looking to casually date, he's looking to get more serious. He's a nice guy, but he can be needy and is definitely looking to settle down. He lost his father about a year ago and that made him want to get married," said an ex-girlfriend of Toth.
Witherspoon, who broke up with Jake Gyllenhaal in December because he was pushing for marriage, has no plans to tie the knot with Toth yet.
"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," said a source.
