Jennifer Hudson feels pressure as an actress after winning an Oscar.

The actress-and-singer earned an Academy Award for Best Supporting Actress for her very first film role as Effie White in 2006 musical drama 'Dreamgirls' and she admits being so successful at the start of her career has made her conscious of her acting in subsequent movies.

She said: ''When I did 'Dreamgirls', nobody was paying attention to me so I had nothing to prove. Now, I'm the 'Academy Award winner, Jennifer Hudson', so everybody is watching.''

The spiritual star - who first came to prominence as a contestant on singing competition 'American Idol' in 2004 - believes her acting career is a ''reward'' for embracing her ''gift'' of singing.

Jennifer, 32, explained: ''For me, music is always there. Music connects me to my emotions. Someone once told me that singing is my gift and acting is my reward for using my gift. God chose to bless me with an acting career because I honoured the gift of singing that he gave me.''

The 'Black Nativity' star has a four-year-old son, David Jr., with her fiancé David Otunga - a WWE wrestling star - and it seems the ambitious tot is eager to follow in both his parents' footsteps.

Jennifer added to the Metro newspaper: ''Right now he wants to be an actor, the next minute a wrestler, the next he is singing. I am so curious to see what he is going to be. I know he is going to take over the world.''
