Kelly Osbourne reportedly wanted to start a family with her ex-fiancé Matthew Mosshart, but he wasn't ready.
Last week the 29-year-old star confirmed she and chef Matthew Mosshart had ended their engagement, although they insisted they remain the best of friends.
It's now been claimed that tensions caused by discussions about family were the root of the issue. Kelly has reportedly felt broody ever since her brother Jack and his wife Lisa Stelly became parents to their daughter Pearl in 2012.
"Kelly was really keen to be a young mom and wanted to start a family this year. She planned to divide her time between the UK and LA with Matt, but he wanted to live in New York and made it clear he wasn't ready for babies yet," a source told British magazine Closer.
"Kelly and Matt have been seeing much less of each other over the past few months and they sat down to have an emotional chat over Christmas, deciding that they just wanted different things. Kelly's been in tears as she's felt broody ever since Jack has his little girl. She worries that her baby dream won't happen for now."
The former couple met at Kate Moss' July 2011 wedding to Jamie Hince. Kelly and Kate are good friends, while Matthew is the brother of Jamie's The Kills bandmate Alison Mosshart.
The Fashion Police star is said to be particularly struggling with the breakup as Matthew was her first romance following her split from former fiancé Luke Worrall. They split after he was accused of cheating on her in 2010.
"Kelly hasn't been in a serious relationship since she went out with Luke and Matthew really made her feel like she'd found The One. She's distraught but her friends and family are rallying about her. She's trying to focus on a positive future," the insider added.
Kelly's mother Sharon has already spoken out about her daughter's latest split, claiming it was the right thing to happen and joking the star is now ready to "audition" prospective partners.
