Beyonce's mother got married at the weekend.

Tina Knowles tied the knot with 'Poltergeist' actor Richard Lawson on a yacht off the California coast last night (12.04.15), TMZ reports.

All the guests at the wedding - including Beyonce, her husband Jay Z, their three-year-old daughter Blue Ivy and Tina's other daughter, Solange Knowles - were asked to wear white to the evening ceremony.

Tina - who split from her daughters' father, Mathew Knowles, in 2009 after over three decades of marriage - was seen arriving at the venue earlier in the day with Beyonce to check out the yacht, before leaving in a black car and returning later for the ceremony.

While it is unknown how many other guests were at the wedding, the yacht had a maximum capacity of 300 people.

The fashion designer recently opened up about finding love with Richard - who has also been married before - after her divorce.

Tina, who started dating the 68-year-old actor in 2013, said: ''I'm at my happiest I've been in a long, long time.''

In June 2013, Tina's ex-husband Mathew married former model Gena Charmaine Avery in his hometown of Houston, Texas.
