Los Angeles, California - Californian adult model Heidi Grey sent her fans into a frenzy on Thursday evening.

In three new pictures, the 22-year-old showed off her curvy underboob as she sat on a staircase wielding a paintbrush.

"Started a new renovation project today! On a scale of 1-10 how great do these railings already look?!" she asked provocatively.

The majority of her fans had the same idea: Heidi Grey could happily drop by their house with a paintbrush.

But it's doubtful anyone was thinking about real painting work, as the model had already set her admirers' imaginations running the day before.

On her Instagram account, she posed in a pink dress, which she then pulled up to expose her bare bottom.
