Former Bachelor Ben Higgins turned 28 on Wednesday and his new fiancée, Lauren Bushnell, celebrated the occasion with a super-sweet Instagram post.

Bushnell, who won Higgins' heart during the most recent season of The Bachelor, shared a pic of three Polaroid photos -- one of herself, one of Ben, and one of them standing together. She captioned the cute snapshot, "HBD to this handsome man. So thankful I get to celebrate with you today and forever!"
