Cops were called to the couple's home in Boca Raton, Florida to investigate reports of an alleged domestic disturbance, according to Tmz.com.
Both Lohan and Major, who are parents to a young son named Landon, have ranted about the incident in a series of posts on Twitter.com, with the actress' father claiming he was the one who called the emergency services.
He writes, "All I want is for her to get help so she can be there for our wonderful son. Maybe this will do it."
The couple became engaged in 2010. Lohan divorced Lindsay's mother Dina in 2007.
