Teresa Palmer has given birth to a baby boy.

The 27-year-old actress and her husband Mark Webber, 33, welcomed their first child into the world on Monday (17.02.14) and have named him Bodhi Rain Palmer.

The couple chose to give the tiny tot Teresa's surname as Mark's five-year-old son Isaac- whom he has from a previous relationship - didn't take on the his last name either.

The 'Warm Bodies' star took to her Instagram account last night (18.02.14) to share the happy news with her fans.

She wrote: ''Thank you God for blessing us with the most divine gift of our baby son. Introducing Bodhi Rain Palmer born safely, lovingly and naturally last night. 8lbs even. Bodhi means ''Enlightened one'' Rain means ''Abundant Blessings From Above'' and we chose Palmer as his last name as Marks son Isaac didn't take his dads name either. Thanks for all the blessings and love everyone (sic).''

The pair first started dating in September 2012 and got married in December 2013 in Mexico, just three months after announcing their engagement and that they were expecting a child together.

Earlier this month, Teresa and Mark tied the knot again, this time legally, but in a Christian ceremony in California.
