(July 4, 1973 - present)
On 14 July 1973, she married Robert Sullivan, an estate agent, Swansea night club manager and Olympic judoka.
After global success in the 1980s, Tyler and her husband Robert Sullivan decided to try to have a baby when she was aged 39. Tyler miscarried and did not conceive again.
Since 1988 Tyler and her husband have owned a villa in Mumbles in Wales. They owned a five-bedroom home in the Algarve (in Albufeira, south Portugal), after Tyler recorded one of her albums there in the late 1970s and where the couple spent the better part of the year. In 2005, Tyler was filmed for a short Polish entertainment TV show called Zacisze gwiazd, which explores the houses of actors and musicians. As of 2009, that house has been knocked down and replaced with a house 10,000 square feet larger house overlooking the Santa Eulália beach in Albufeira.
Tyler and her property-development husband have invested in real estate—as of a 1999 interview, they owned farmland in Portugal and New Zealand, 22 houses in Royal Berkshire and London, and 65 stables offering horse boarding services. In a 2013 interview, Tyler stated that the farm in New Zealand had been converted to a dairy farm 12 years after they originally purchased the land. In the same interview she also stated that she owns a quarry with her husband.
Through her husband, Tyler is related to actress Catherine Zeta-Jones and attended her wedding to Michael Douglas, performing "Total Eclipse of the Heart".
