Jennifer Aniston has reportedly spent $50 million on Justin Theroux since they began dating.

The actress has been romancing Justin for around a year, after they met on the set of their movie Wanderlust.

It's known that the Hollywood actress enjoys treating her partner, as she has previously bought him a $12,000 leather jacket and a painting worth $450,000.

According to the British edition of Grazia magazine, Jennifer's treats already total $50 million.

"Neither Jen nor Justin seem embarrassed that she is the main breadwinner. She's in a comfortable position, so why not spend money on the man she loves?" a source told the publication.

Among the other items Jennifer has splashed out on are two motorbikes totalling $57,000 and furniture and other home decorations which cost more than $1 million.

She has also paid for a $9 million home which they share in New York City, and spent $4 million on renovation work. Jennifer then snapped up a $21 million home in Los Angeles, which is thought to have cost $10 million more to get into the shape she wants.

Further money has been lavished on holidays, hotel stays and flights.

Justin is also a fan of lavishing Jennifer with presents. "Just loves buying Jen little gifts and going out of his way to show how much he cares," the insider said. "This is not a one-sided relationship at all, and Jen feels she is the luckiest girl in the world."
