Jonah Hill has been spotted engagement ring shopping.

The 'This Is The End' actor reconciled with Jordan Klein - who he dated for four years before they split in 2011 - in May and the renewed relationship has reportedly gotten so serious that Jonah is ready to tie the knot.

A source told America's Star magazine: ''He knows she is the right girl for him. She knew and loved him before he was famous and he has realised how important that is and he's ready to commit.''

In September, Jonah and Ali Hoffman called time on their relationship after nine months together.

'Moneyball' star Jonah was said to have been close to 24-year-old Ali - the daughter of actor Dustin Hoffman - for some time before they started dating, and even went to the same school, Crossroads High School in Santa Monica, although they were in different years.

Dustin also had a hand in Jonah's career, spotting him while he was still in high school and helping him land his first role in 'I Heart Huckabees'.
