Jason Sudeikis is reportedly ready to ask for his girlfriend Olivia Wilde's hand in marriage.

The Horrible Bosses star has been dating the House actress for nearly a year now.

The pair are said to have moved into a $3 million luxury home in the Soho area of New York City recently.

Jason is absolutely smitten with Olivia.

"Jason is head over heels for Olivia," a source told Star magazine.

Their romance continues to blossom and Jason is said to be considering popping the question by the end of the summer.

Apparently Jason has known from the beginning that Olivia is the woman he wants as his wife.

"He's been saying since day one that he was going to marry her, and if it were up to him, they'd already be hitched!" the source revealed.

Jason is said to have been consulting with NYC based jewellery designers on creating a beautiful engagement ring for Olivia.

Jason was previously married to Kay Cannon, but they divorced in 2010 after spending six years together.

Olivia is also a divorce as she called it quits with ex-husband Tao Ruspoli, an Italian filmmaker, in 2011.
