A source recently revealed to E! News that the soon-to-be parents are in "no rush" to get married anytime soon.
"They already feel married and don't feel they need a signed document to seal the deal," explained the insider. "They eventually do want to get married and have a ceremony but for now, are focused on their baby girl coming."
The source also said that the couple is a "true modern family" and that Matthew acts as a great stepdad to her son Luca (who she shares with ex-husband Mike Comrie).
