Adam Dell is a proud papa with photographs of his daughter, Krishna, all over his house in Austin, Texas — and he wants a larger role in his child’s life. The venture capitalist is said to be negotiating with Padma Lakshmi for visitation rights, weekends and vacations with the little girl. A source said Dell told guests at a barbecue at his home “how excited he was to raise her, but that Padma wasn’t being entirely accommodating.” A friend of Lakshmi snips back, “An agreement was made with the biological father that was very fair. It’s unfortunate if anything inappropriate is being said.” Her rep could not be reached. Dell’s spokes man, Howard Rubenstein, had no comment.
