pbr The showbiz world has been reacting to the news that comedians Dawn French and Lenny Henry have split up after 25 years of marriage.br ppbr Speaking at a fashion event in London, former EastEnders actress Michelle Collins said: "I am sure they want it to be private but it is very sad when a very long relationship like that breaks up."br ppbr TV presenter Gail Porter also shared her feelings: "It is sad. They made such a nice couple. That is a shame. It is horrible when anyone splits up."br ppbr Meanwhile former Blue Peter presenter Konnie Huq had a more philosophical view on the showbiz break-up: "I have a theory that in the future, marriages will be things people go in and out of - my first, my second, my third. It is evolution of society I guess."br ppbr 51-year-old Jenry and 52-year-old French married in 1984 and have an adopted daughter called Billie.br ppbr According their spokesperson, the split was "entirely amicable" and they hope the media will now respect their privacy.
