The X-Men Origins: Wolverine star and her Irish dancer husband Tristan MACManus welcomed their daughter Echo on Tuesday (05Apr16).

She announced their good news on Instagram by sharing a picture of their baby's full name handwritten on a piece of paper. In the caption, she writes, “Our baby girl Echo Isolde MACManus was born 05/04/2016 healthy and happy. Tristan & I are so thankful for everyone’s support."

The 29-year-old's model sister Cheyenne Tozzi let slip about Tahyna's pregnancy on Instagram in February (16) by posting a photo of her touching her sister's bump, writing, “I love you and baby too."

Cheyenne has since written, "Welcome baby girl Echo Isolde MACManus @tahynavalentina."

Tahyna, a former model and star of Australian teen series Blue Water High, married Tristan in 2014. Tristan has appeared on TV shows Strictly Come Dancing and Dancing with the Stars.
