Jennifer Hudson is convinced her seven-week-old baby talks to her.

The singer, who has a son, David, with fiance David Otunga, is adamant her offspring is a genius and is already trying to converse with her.

“He’s a very rare newborn. He tries a lot - he’s turning over, he’s lifting up his own head, he tries to hold his own bottle, sometimes I swear he’s talking to me, or at least trying to,” the 28-year-old said. “The other day he said, ‘Hi!’ - I swear, I’m not crazy. David was there too, and he was like, ‘He just said, Hi!’ He’s very aware.”

Jennifer is inspired to be a good parent by her own mother - who, along with the singer’s brother Jason, was killed last year by William Balfour, the estranged husband of Jennifer’s sister Julia.

She is determined to give David the best start in life, and is already investing in special outfits for him to wear on his first Halloween. “It’s going to be ridiculous. I can’t wait. His dad went and bought him some Halloween stuff the other night. I wish he was older so he could remember it, but this is the first one, so I have to go all out. It’s going to be great,” Jennifer explained to People magazine.

The “Spotlight” singer thinks David might even follow in her footsteps by becoming a musician. “The other night he was having a fit screaming, and someone turns on the music and he just stops and calms down. Sometimes when he cries, I try to harmonize!” she said.
