It’s your wedding day. You’re standing at the altar, ready to say "I Do" to the love of your life when you look out at the crowd and see… someone you used to date. Awkward much? 

Maybe not. Wetpaint Entertainment has learned that Desiree Hartsock – who came in fourth on Sean Lowe’s season of The Bachelor – will attend Sean’s January 26 nuptials to winner Catherine Giudici.

“Desiree is coming,” a source confirms to Wetpaint. When we last spoke to Des, back in October, she said there was one major thing standing in the way of her attendance. “We haven’t been invited yet,” Des explained, “but if we are then we will definitely support them and go.” Glad they got that cleared up!

And it’s not as weird as you might think. Des will, of course, be bringing her fiancé, Chris Siegfried – winner of her season of The Bachelorette – with whom she’s madly in love. And it goes without saying the only woman Sean will be looking at is the one he’s marrying.

Still, we’re told it wasn’t exactly Sean and Catherine’s idea to invite Des. “It was ABC’s,” the source confides. “They like having all their ‘success stories’ at major events like these and Des and Chris are the latest ones.” 

That said, “both Des and Sean are very happy in their own relationships,” the source confirms. “There are absolutely zero feelings left between them. They’re just happy for each other.”  

And we're happy for all four of them! Here's hoping Des and Chris are the next pair to tie the knot on TV!
