Mukesh Ambani's 27-year-old daughter Isha Ambani said she and her twin brother Akash Ambani were born through IVF process, seven years after their parents' marriage. "When my mother (Nita Ambani) finally had us she wanted to be a full-time mum initially," said Isha. "She resumed work when we were five, but she was still a tiger mom," Isha added.
