Kody Brown and his fourth wife Robyn have welcomed their first child together.

Baby boy Solomon became the 17th addition to Kody's brood yesterday (26.10.11), which includes three wives and 16 children, some from previous marriages, who star on TLC reality TV show 'Sister Wives'.

Speaking about his latest arrival - who weighed 9lbs 10.5oz and is 22-inches long - Kody told People magazine: "He's perfect and we couldn't be happier. We are so thrilled."

The Brown clan - who moved from Utah to Nevada after police launched an investigation into the family last year - are currently residing in four separate homes in Las Vegas and they are said to be dealing with emotional, financial and physical strain due to their "plural" lifestyle.

Kody and Robyn tied the knot during last season's final episode of 'Sister Wives', which is set to air the birth of Solomon on November 27.
