Lindsay Lohan is a sister again after dad's fiancee gives birth

Lindsay Lohan is a sister all over again - her dad Michael's fiancee Kate Major has given birth to a baby boy in a Florida hospital.

The tot was born as the actress was leaving court in Los Angeles after the latest hearing into allegations she lied to police officers investigating a traffic accident she was involved in last year (12).

Reality TV star Michael and his bride-to-be have named their firstborn Landon Major Lohan.

TMZ.com reports the proud new dad was by his fiancee's side throughout the delivery.

As well as Lindsay, Michael Lohan has a daughter, Ali, and two sons, Cody and Michael, Jr., from his marriage to ex-wife Dina. He also fathered a lovechild with a former mistress, Kristi Horn. A televised DNA test last year (12) proved he was the biological father of her daughter Ashley, 17.
