Lydia and Zhenya Tsvetnenko have reason to celebrate this week - the multi-millionaire power couple welcomed baby daughter Max Alice into the world on Tuesday.
Zhenya revealed to AAA late last year that he and his fashion designer wife were expecting a baby girl - their first child - but they were keeping names quiet.
Lydia was expected to give birth on Australia Day but Zhenya confirmed on his Facebook page that the bub had come a week early.
"Mum and baby are doing great," he wrote.
Despite being heavily pregnant, Lydia was still spotted out and about at various Perth social events.
The couple reportedly have a fortune that is worth nearly $115 million.
