Prime Minster, Portia Simpson Miller and Barbadian Superstar Rihanna amongst Time "Most Influential People in the World".

Time Magazine has hand-picked a slew of celebrities who "inspired, entertained,challenged us and change our world" to be on the list of  The 100 Most Influential People in the World.

Jamaican Prime Minster, Portia Simpson Miller and Barbadian Superstar Rihanna are two such icons who make up this year's TIME 100.

Portia Simpson Miller

This is what  Yvette D. Clarke, is a Congresswoman for New York's 11th District,  had to say about Jamaica's first female Prime Minister

Prime Minister Portia Simpson Miller — or Sister P, as I affectionately call her — is the embodiment of perseverance and strength. She will have a profound impact as she strives to be a transformational figure in Jamaica.

Portia, 66, started her career as a public servant in local government in 1974. Two years later she was elected to the Jamaican Parliament.

In 2006 she made history, becoming the first woman to be elected Prime Minister of Jamaica. She was re-elected in December 2011. While she has worked for many years as a public servant representing all Jamaicans, there is a great sense that her leadership will expand far beyond her island nation. In addition to her call this year to break with the British monarchy and make the island a republic, Portia is promoting full civil rights for gays and lesbians, a courageous move in a country with a violent history of homophobia.

I can say from personal experience that her presence is already inspiring a new generation of women, particularly from the Caribbean diaspora, to get involved in public service and to make a difference. Sister P is a woman to watch.

Rihanna

This is what Fashion designer Stella McCartney told Times about Rihanna

I can't remember when Rihanna and I first met, but I think it was near a dance floor and one of her tracks was playing. The thing I remember was her being a normal person, not what you'd expect of a young woman about to take over the world. She's one of the coolest, hottest, most talented, most liked, most listened to, most followed, most impressive artists at work today, but she does it in her own stride. She works hard, very hard. She gives to her fans, friends and foundation not just herself but her energy and spirit.

Rihanna, 24, goes out of her way to support the people she believes in. She is one of the few people I know in that world of fame and celebrity who aren't all about themselves. She'll give a real part of herself to an ordinary person she may meet, and that's rare

.

This is the beginning for Rihanna — she has so much more to do and to give. She is just getting going, so watch out. She's the Barbados ambassador for youth and culture, and she's coming to a town near you.

World fastest man Usain Bolt was also nominated, but did not make the official list.
