We’ve been following Catelynn Lowell’s quest to lose some weight and get healthier very closely (she’s almost reached her goal weight of 120 pounds!), and we were happy to see that the Teen Mom star recently posed for a picture in a cute, striped summer dress — which showed off her slim frame perfectly.

Even Catelynn’s devoted fiance, Tyler Baltierra, couldn’t believe his eyes!

Tyler tweeted the above picture of his sweetie and wrote, “Isn't she beautiful! God I love that woman #soulmate.”

Not only do we agree with Ty that Catelynn looks amazing, but we just can’t get enough of this beyond adorable couple! They support each other 100 percent — soulmates indeed!

What do you think of Catelynn’s summer look?
