Despite playing a wife in many films, Maria Bello hasn't understood the appeal of matrimony until recently.

The "Mummy" actress and her boyfriend Bryn Mooser have become engaged, reports People.

The engagement was announced in Bello's hometown newspaper, The Norristown Times Herald (in Norristown, Pa), which explained that the couple "fell in love over a sheer passion of politics, Africa and cryptozoology."

Bello, 41, and Mooser, 28, have not set a date yet. Bello has a son called Jackson Blue, born in 2001, with ex-boyfriend Dan McDermott.

Previously, Bello had told Page Six that she was "always anti-marriage. I didn't understand monogamy. I couldn't figure out how that could last. And then I met Bryn and I started to understand the beauty of constancy and history and change and going on the roller coaster with someone -– of having a partner in life."

Bello is a two-time Golden Globe nominee for her film work and the winner or a Screen Actors Guild prize as part of the ensemble cast of "E.R." Most recently seen in "World Trade Center," "Flicka" and "The Jane Austen Book Club." She next replaces Rachel Weisz as the wife of Brendan Fraser in "The Mummy: Tomb of the Dragon Emperor," which hits theaters on Friday, Aug. 1.
