Singer Michael Buble and actress/model wife, Luisana Lopilato, are expecting their first child and surely are very excited about it. The baby news was announced on YouTube through Lopilato's account. The 20- minute video shows the sonogram, which ends with the words, "We're having a baby Buble!!!!"

The news was later confirmed to foxnews.com by the couple's representative. This will be the first child for the couple who married in 2011.

Buble has gained worldwide fame with his melodious songs and has often written tunes in dedication to his Argentine wife. He co-wrote the song "Haven't Met You Yet" for the 25-year-old, who also appeared in the song's music video.

He has also written a number of songs for the women he dated before his wedding to Lopilato. Buble has previously dated stage actress and singer Debbie Timuss and was also engaged to her. The song "Home" is said to have been dedicated to Timuss. Later the 37-year old was linked to British actress Emily Blunt who lent her voice for the cover of "Me and Mrs. Jones" in the album "Call Me Irresponsible." The song "Everything" was dedicated to Blunt.

Considering the Canadian singer has almost a ritual of penning songs for his loved ones, we are sure he is hard at work writing a song for the child who might be welcomed into the world with Buble's soothing voice.

Announcing pregnancies online is a trend that is fast catching up these days. One of the most popular celebs to use the social media to announce her pregnancy and keep fans updated is Jessica Simpson. She not only announced her pregnancy on Twitter over Thanksgiving but even posted a picture of her baby bump a few days later.

Shakira and boyfriend Gerard Pique used the social media to post a picture of her baby bump and even had a virtual baby shower in aid of a worthy cause.
