Instagram 'Belfie' Sensation Jen Selter Lands Another Endorsement Deal

Jen Selter, the New Yorker whose amazing ass brought her fame and now fortune on Instagram, has -- as we knew would happen -- signed yet another marketing partnership deal. This time, it's Cirrus Fitness, a fitness equipment manufacturer.

If you haven't heard, or have been living under a rock, a couple years ago Selter began working out. She noticed it was firming up her body, most notably, her butt. So she decided to post posterior pictures, of belfies, to her Instagram account. She now has 2.2 million followers. Most probably following for reasons entirely separate from fitness-related purposes.

Of her new deal with Cirrus, Selter said, "I believe in motivational fitness. Cirrus equipment has personality, it is fun and it will help people be active. Cirrus makes great durable products that I'm proud to share with my followers, and I can't wait to start developing my line of products."

Selter already has deals withNew York water brand NY20 as well as nutrition supplement company Game Plan Nutrition.

According to the agreement, Selter will collaborate on a custom Jen Selter line of fitness products to launch later this year, focusing on helping all levels of fitness enthusiasts achieve their healthy lifestyle goals. Selter will use Cirrus products and will promote the brand on her social media channels by sharing workout tips and videos, featuring Cirrus Fitness yoga/exercise mats, stability balls and medicine balls in workout programs. Selter will also host product giveaways via her social media channels.
