Congratulations are in order for Cameron Diaz and Good Charlotte star Benji Madden who are engaged after a whirlwind seven-month romance.

A number of sources confirmed the couple’s amazing news to Us Weekly, saying that the loved-up pair are naturally thrilled.

“Everyone thinks it’s wild but are so happy for them. Benji always tends to fall in love easily, but this time it’s for real and he landed a great girl,” said one source.

“They obviously both make each other incredibly happy and there’s nothing better than that,” they added.

News of the couple’s romance spread back in the summer, with Benji’s sister-in-law Nicole Richie apparently introducing the pair.

Speaking in an interview on Watch What Happens Life, the 33-year-old said: “I approve of anything that’s going to make Benj happy. I’m going to take responsibility for everything!”

With Cameron’s mum Billie already said to be a huge fan of rocker Benji, it looks like these two are very well matched.

Congratulations to the couple. Now, when do we get a look at the ring?

There may be wedding bells in the air for Cameron Diaz and her boyfriend Benji Madden!

Cameron was spotted with quite the diamond on her left-hand ring finger when she attended an event in Hollywood and then later out on a dinner-date with her man.

The couple have been together since April, after being introduced by Benji’s sister-in-law, Nicole Richie.

The former reality TV star turned designer is married to Benji's brother and Good Charlotte frontman, Joel Madden, the couple have two children together, Harlow and Sparrow. 

Nicole joked recently that the relationship was entirely her doing, saying: “I’m going to take responsibility for everything. I approve of anything that’s going to make Benji happy.”

Aww – how sweet, we wonder if Nicole will design Cameron’s wedding dress…or are we jumping ahead of ourselves?!
