Sister Rivalry! Kate's Revenge! Could Middleton Upstage Her Sister’s Wedding With A Baby Announcement?

Kate Middleton might have a big secret! She was spotted hiding her stomach in a large blue coat at a festival in Luxembourg, possibly covering up a baby bump? If it is, she'd definitely steal all the attention away from her littler sister Pippa Middleton's wedding!

Kate has been hands-on with her sister's wedding planning, but could soon have some big news of her own!

In a light blue coat, the mom of Prince George and Princess Charlotte clutched her purse over her stomach while at the festival this week.

She looked a lot better than she did a few weeks ago when she was scary skinny. Maybe because there's a bun in the oven?

She debunked pregnancy rumors in March when she was seen drinking beer with the boys. But she definitely didn't have a drink in hand at this festival.

Do you think Kate is pregnant with baby #3? Sound off in the comments!
