Mark Wahlberg has cleared up the reason why he wasn't at brother Donnie's wedding to Jenny McCarthy - because it was his daughter's birthday.

The Ted actor explained in a video posted on Facebook that his no-show was not because he didn't want to be there.

He said: "Congratulations, guys! Congratulations from all of us. Wish we could be there - it's Ella's birthday today. She's 11 today.

"I love you, Donnie. Very happy for you. Sorry we can't be there. We'll see you soon."

The video showed Mark, his wife Rhea Durham and their four children all gathered together at home to pass on their best wishes to Donnie and Jenny.

Mark also made sure Donnie got his message by tweeting the happy couple: "Congratulations @DonnieWahlberg and @JennyMcCarthy, so happy for you both today."

Donnie showed there were no hard feelings by replying: "Thank you @mark_wahlberg. Thanks to you and @rheadur for the adorable video for me & Jenny! Please wish a Happy B-Day to my god daughter Ella!"

The groom also thanked his New Kids On The Block fans, known as Blockheads.

He tweeted: "To my darling BHs...Every tweet. Every thought. Every wish. Every kind word. Every kind gesture. Means so much. Thank you! #loveeternal."
