‘We ask that you please respect our privacy during this celebratory time for us and our families. There truly is love out there for all. We hope ours is the ember of yours, as we feel yours is the ember of ours.’

The ecstatic message was accompanied by two photos of the parents-to-be, including one of Johnny and Alaina sharing an embrace on the beach.
Johnny and Alaina only went public with their romance on social media in September, and two months later made their red carpet debut in November at the E! People’s Choice Awards.
Since debuting their romance, the May-December couple have not shied away from posting loved-up snaps onto their Instagram accounts.
Johnny previously dated his Big Bang Theory co-star Kaley Cuoco.

Not only did the couple date for two years, but they also played each other’s love interests on the comedy show.
The pair split up in 2009 and Kaley went on to marry pro tennis player Ryan Sweeting in December 2013.
Following the end of her marriage to Sweeting, the actress, 33, went on to tie the knot for a second time with equestrian Karl Cook this past June.
