Brothers or sisters in a similar line of work may display professional rivalry. In serious drama, conflict between siblings can be fatal, as shown in crime dramas involving such rivalries. Real life
Occasionally real life instances of sibling rivalry are publicized in the mass media. Siblings who play the same sport will often be compared with each other; for example, American football players Peyton and Eli Manning, or tennis players Venus and Serena Williams. Musicians Liam and Noel Gallagher of Oasis have a turbulent relationship, similar to that of Ray and Dave Davies of The Kinks. Politicians Ed and David Miliband are likewise portrayed as having a strained relationship, after Ed narrowly defeated David in the final round of the 2010 Labour Party leadership election (UK).Actresses Olivia de Havilland and Joan Fontaine had an uneasy relationship from childhood and in 1975 the sisters stopped speaking to each other completely. The incredibly popular singing Andrews Sisters maintained professional harmony in show business for more than 30 years, but clashed famously in their personal lives (after LaVernes death in 1967, Patty and Maxene stopped speaking in 1975 and never looked back). The rivalry between singers Lata Mangeshkar and Asha Bhosle is often talked about in the Indian media, in spite of their insistence that these are just tales. Twin sisters and advice columnists Ann Landers and Abigail Van Buren had a relationship that was alternately very close and publicly antagonistic.
