As her hit show comes to an end, Jessica Paré is getting ready for a new beginning: She’s pregnant!

The Mad Men star is expecting her first child with boyfriend John Kastner, her rep confirms to PEOPLE. 

The happy news apparently flew under the radar for a while: Last month, Kastner, a musician, posted an Instagram photo of him and Paré, 33, hugging as his 7-year-old daughter Summer Lee proudly wore a T-shirt reading “I’M GOING TO BE A BIG SISTER.”

The stars, who are both Canadian, began dating in May 2012.

Lol @ his hair.

He doesn’t look nearly as happy as Jessica and the little girl. Doesn’t bode well.

Some people just don’t realize when they look ridiculous.

he’s just a liiiiittle too old for that style. That is for the under 30 crowd John…time to adjust.

His hair is in Dredlocks — interesting. I’ve only seen Jamaican men and African American men wear their hair in “Dreds”. I wonder what made him wear his hair that way?

I’ve seen many white men/women with dreads… And I don’t think much about them, as I do any other color men/women that wear them.

To each his own…
