'Bachelor' Sean Lowe's cutest Instagrams to celebrate his 30th birthday

sean-lowe-chris-harrison-shirtless.jpgAdorable former "Bachelor" and "Dancing With the Stars" contestant Sean Lowe is celebrating the big 3-0 Saturday (Nov. 16), so in honor of the golden boy's birthday, we've rounded up his cutest Instagrams -- most of them involve fiancee Catherine Giudici, too. Of course, because she is the cutest thing ever.

But the one above may be our all-time favorite. It's Lowe and "Bachelor" host Chris Harrison preparing for an interview -- and as a joke, Lowe is shirtless. Yay for Shirtless Sean!

It's going to be a big few months for Lowe. He's turning 30 and in a few short weeks, he'll marry Giudici on live television on ABC. The live festivities air from 8 p.m. to 10 p.m. on Sunday, Jan. 26, 2014.

Happy birthday, Sean!
