Guy Ritchie and Jacqui Ainsley are reportedly engaged.

The 'Snatch' director - who was previously married to Madonna - is said to have proposed to the 30-year-old beauty and the model showed off a huge round-cut diamond ring on her engagement finger when the couple dined at Los Angeles' Madeo restaurant on Sunday (07.10.12), UsWeekly.com reports.

Jacqui - who has been in a relationship with Guy since April 2010 - is currently pregnant with the couple's second child.

As well as having 13-month-old Rafael with Jacqui, Guy also has sons Rocco, 12, and seven-year-old David with Madonna.

The 44-year-old filmmaker - who split from Madonna in 2008 after eight years of marriage - has previously said he ''enjoyed'' being married to the singer and has no regrets.

He said: ''I enjoyed my first marriage. It's definitely not something I regret. The experience was ultimately very positive. I love the kids that came out of it, and I could see no other route to take.

''But you move on, don't you? You're right, I stepped into a soap opera, and I lived in it for quite a long period of my life. I'll probably be more eloquent on it 10 years from now.''
