According to the National Enquirer, the actor has been romantically involved with Bonnouvrier since he left jail in January after serving a 48-day term for DUI.
"Jail was the best thing that ever happened to Kiefer," said a source. "It scared him straight.
"Kiefer's finally grown up - and part of his turnaround is due to Siobhan. Siobhan is an amazing woman, and she's transformed Kiefer in just a few short weeks.
"She isn't the least bit fazed by Kiefer's fame or by his wild past, and the relationship has blossomed."
They added: "It's a little premature to talk marriage. They both are looking for a long-term, serious commitment."
