Happy Endings may have ended on ABC, but the “happily ever after” continues for one of the sitcom’s stars and its creator.

Casey Wilson, 32, who starred as hapless romantic Penny Hartz on Happy Endings, is engaged to show creator David Caspe, 34 … and the couple has been since Labor Day weekend, PEOPLE has confirmed.

The private couple, dating for two years, is just now announcing the news, however.

Wilson showed off her engagement ring – a pear-shaped diamond with smaller diamonds around the band – at a Beverly Hills pre-Emmys party that the couple attended on Friday.

The former Saturday Night Live cast member has a busy schedule ahead of her: Wilson is appearing in the upcoming films Me Him Her and Claire’s Cambodia.
