Michelle Trachtenberg thinks Blake Lively was ''definitely meant to be a mother.''

The 29-year-old actress says her former 'Gossip Girl' star, who welcomed a baby girl into the world with husband Ryan Reynolds last month, was always ''maternal'' towards her cast-mates on the set of the series.

Asked about the blonde beauty's new bundle of joy, she said: ''I think throughout my many years with Blake she has always exuded charm and exquisite elegance and a maternal side. So I think she's definitely meant to be a mother.''

Michelle also told E! News she has no doubt that the 27-year-old actress' daughter is a good-looking baby.

Blake recently admitted becoming a mother felt very natural.

The 'Savages' star said: ''I always felt like a mama...

''I don't feel like it's a massive change.''

She also revealed she is already planning to have another baby.

She said: ''I do want to just enjoy this moment. But I also feel like my first child is going to be the oldest sibling to the next kid, and that may change with each and every year.

''I'm looking forward to how one baby influences the other, and to my family as a whole, to every single chapter.''
