The actress took to Instagram to share the lovely news with fans, announcing she welcomed a baby boy on Thursday 11th February. The couple also revealed the baby's name - Owen Bartlett Hubbell.
Posting a beautiful picture of her and her newborn baby lying on her chest, Heather wrote: 'Owen Bartlett Hubbell 7 lbs 3oz born 2.11.16...I can't tell you how amazing an experience to go from a cesarean and having a VBAC...but I did it with the loving help of my husband, Dr and family :) and of course this little guy'
In the post, Heather also said she experienced a natural birth this time, after having had a c-section for her first son.
The 28 year old announced her second pregnancy last August, also via Instagram. In the last six months, the expecting mummy remained active while she waited her new arrival, and even committed to a daily walking workout until giving birth up until three weeks ago.
She revelead she was having a baby boy during an interview in November, and spoke of how she thought her eldest son Elijah was going to react to being a big brother.
'He's really cute around babies and baby dolls so I think he's really gonna adore it', she said. 'He's really excited to have somebody to play with because he's at that age where he's active and wants to do stuff.'
Heather starred in the American hit TV show Glee between 2009 and 2015
The former Glee star, who played the role of Brittany for six years alongside Lea Michelle and the late Cory Monteith, married Taylor in May 2015, in an intimate wedding in California.
Taylor and Heather tied the knot last year
Elijah, their eldest son who they welcomed in 2013, was also at the wedding ceremony.
The mum-of-two has previously said he was a great sleeper, so we're crossing our fingers she has the same luck with the second one.
'He gets about 10 hours of sleep a night', she told US Weekly. 'I go to bed about an hour afterwards. So I get eight or nine hours.'
When she announced she was becoming a mum for the first time, Heather made it clear family is her top priotity. Speaking to Fitness magazine in 2013, she said: 'I want to marry Taylor and have kids with him. I love acting, but if it affects my relationship, then I won't continue.'
Congratulations to the happy family!
