The spouses-to-be celebrated their engagement Monday evening at Beverly Hills eatery Mr. Chow. Gilbert, who became a child star as Laura Ingalls on "Little House on the Prairie" in the '70s and '80s, admitted last year during her stint on "DWTS" that her split from her second husband, Boxleitner, after 16 years together, was a challenge.
