Christine Baumgartner flaunts her $50,000 engagement ring as she moves on from Kevin Costner who brags of his wild single life on Instagram

Positively beaming, Kevin Costner’s ex Christine Baumgartner has been showing off her new massive bling around her stomping grounds in California.

Whether running her teenage daughter Grace to do errands on Coast Village Road in Montecito or stepping out with a girlfriend for some shopping at the K. Frank boutique just down the street, Christine appears happier than ever.

And why shouldn’t she be?

The 51-year-old has a lot to smile about since getting engaged to financier Josh Connor two months ago.

And the ring is of such quality that it could be seen refracting light from 50 feet away as these exclusive DailyMail.com photos show.

Sporting a cap that read ‘Montecito’, Christine briefly put her hand on her head as she walked with Grace, 14, on March 5.
