​Jessica Paré welcomes baby boy Blues Anthony

Mad Men star Jessica Paré and her musician beau, John Kastner, have welcomed their first child together – baby boy Blues Anthony. The 34-year-old Canadian actress reportedly gave birth last week and shared the happy news with fans on March 21 via social media.

"Please meet Blues Anthony Paré Kastner…" wrote John, who is also Canadian, on Instagram. In the snap, the proud dad’s eight-year-old daughter from a previous marriage, Summer Lee, holds her newborn baby brother in her arms.

Though the happy couple have yet to speak out on their choice of baby name, the colourful moniker seems to be picking up steam in Hollywood circles. It calls to mind another celebrity tot – Beyoncé and Jay Z’s daughter, Blue Ivy, who was born in 2012 - although Jessica and John have given their son's name a more musical twist.

Jessica, who hails from Montreal, Quebec, managed to keep her pregnancy under wraps until October 2014.

The brunette beauty was previously married to writer-producer Joseph M. Smith for three years before they divorced in 2010. Jessica and John, who is the frontman of punk band Axwell, have been dating for two years.

Having originally auditioned for a minor role, the actress joined the Mad Men cast in 2010 as a secretary at the fictional Manhattan advertising agency, Sterling Cooper Draper Pryce. She quickly became a central character after the shocking season four finale when she wed handsome Don.

Aside from her ongoing Mad Men role, Jessica recently appeared in comedy sequel Hot Tub Time Machine 2.

The final season of Mad Men premieres April 5 on AMC.
