Congratulations are in order!

Rachel McAdams, 39, and screenwriter boyfriend Jamie Linden, 37, have reportedly welcomed their first child together, a baby boy.

Few other details have been made available, which is no major surprise considering the veiled nature of McAdams’s pregnancy.

The Mean Girls actress made her last public appearance at the Toronto International Film Festival back in September, stepping out for the premiere of her film Disobedience alongside co-star Rachel Weisz.

She even skipped the February premiere of Game Night, which she stars in alongside Jason Bateman.

McAdams has yet to comment on or publicly confirm her pregnancy, no less the birth of her son.

However, Disobedience will premiere at N.Y.C.’s Tribeca Film Festival in the coming weeks, so there’s a chance Rachel will use the screening as an opportunity to make her post-baby debut.

Congratulations again to the new mom and dad! As Gretchen Weiners would insist, having a baby is SO. FETCH.
