Very exciting baby news for Lindsay Lohan!

It looks like 2015 will be a busy year for actress Lindsay Lohan now that she’s become a big sister again!

Lindsay’s father Michael welcomed a new baby boy into the family on New Year’s Eve and Michael and his wife Kate Major have told US Weekly that they are ‘ecstatic’ about the new addition.

Lindsay’s rocky relationship with her father has been well documented over the years and while not commenting specifically on the arrival of  her new sibling, the Mean Girls star did take to Twitter to post a positive, upbeat message, saying: “xoxoxox grateful for my family, friends and a new year to come with lots of work!”

Michael, on the other hand, was a little more vocal about his son Logan’s arrival, saying: “What a way to bring in the New Year!”

We’re sure Lindsay and her other siblings are over the moon about having a little baby to dote on!
