Bachelor 2012 Courtney Robertson spotted wearing engagement ring. Courtney Robertson had worn an engagement ring long before she met Ben Flajnik on The Bachelor, but it was actually just for a jewelry company’s ad campaign! HollywoodLife posted the pics today, featuring Courtney wearing a ton of bling!

The 28-year-old Arizona native and model shot several Hearts on Fire jewelry ads in the past. The ads, obtained by Life & Style magazine, show Courtney wearing a diamond band in a series of seductive poses with a male model.

Courtney shot the images for these ads prior to being cast for the reality show. “She did this a few years ago,” a source tells Life & Style.

As we’ve reported Courtney is said to win The Bachelor and gets engaged to Ben. However, there will be some obstacles on the way, especially on tonight’s episode when Kacie shows up! Follow us on Facebook by clicking here.
