Daniel Radcliffe and Jonathan Groff play big roles in castmate's wedding

Daniel Radcliffe and Jonathan Groff played big roles in Lindsay Mendez's wedding.

The Tony winning actress and musical theatre star included her 'Merrily We Roll Along' castmates in her nuptials earlier this week as she tied the knot with actor J. Alex Brinson.

On Monday (22.04.24), Jonathan officiated the ceremony, while Daniel served as the official ring bearer, as seen in photos from the wedding on Instagram.

Lindsay met her husband while working on CBS drama 'All Rise', and they announced their engagement last Christmas (25.12.23).

Meanwhile, the loved up couple are also expecting a child together, and they revealed the happy news on Instagram alongside a photo of crocheted baby booties.

Lindsay - whose three-year-old daughter Lucy from a previous relationship was a flower girl - took to Instagram earlier this month to make the announcement.

She wrote: "Our family band is expanding! And we are bursting with joy! J and I can't wait to make Lucy a big sister and welcome our new baby this fall.

"I'm also so grateful for the unrelenting support of my @merrilyonbway producers and company.

"Together, they have made it so that I can happily work safely, all while growing this true Broadway baby.

"So, I will be continuing with the show, and finish the run on July 7th with my incredible cast. Come see (both) of us at the Hudson!"

Lindsay, Daniel and Jonathan are starring on Broadway in 'Merrily We Roll Along', a musical based on the 1934 play of the same name by George S. Kaufman and Moses Hart.

The show follows the lives of friends Frankilin Shepard (Jonathan), Charley Kringas (Daniel) and Mary Flynn (Linsday) over two decades, and their story is told in reverse chronological order.

'Harry Potter' actor Daniel's stint comes after a busy 2023, following roles in 'Miracles Workers', 'Mulligan' and 'Digiman!', while he has set to join Ethan Hawke and Jessica Biel in upcoming drama 'Batso'.
