The singer tied the knot to her boyfriend Sam Asghari last Thursday. Bryan Spears, who was the only member of her family to be invited, says the date unfortunately clashed with his daughter's graduation from school so he couldn't attend both.
Bryan, who is 45, said his little girl Lexi was so excited about her elementary graduation, he couldn't let her down. She was finishing 5th grade and moving into middle school. He said "we are so sad to miss such an important but so happy for Britney and Sam's marriage".
