Talk about under the radar.

Before the celeb-watching world even had the chance to speculate on wedding themes, mother-to-be Jessica Alba has gone and very quietly tied the knot with Cash Warren.

The actress' rep confirms to E! News that the comely twosome made it official on Monday, though its unclear where the ceremony took place or how many of their loved ones comprised the guest list.

As it is, the low-key couple has long kept mum on the finer points of their private life, only reluctantly confirming their engagement last December, just weeks after announcing their pregnancy.

The camera-ready couple first met in the fall of 2004 on the set of the Fantastic Four, where Warren worked as the director's assistant.

Their nuptial news, first reported by People, marks the first of two big announcements the 27-year-old actress and 31-year-old entrepreneur are expected to make this spring.

Still to come is the birth of their first child, whom guests at her baby shower last month confirmed was going to be a girl.
