The `Till The World Ends` singer - who split from husband Kevin Federline in 2006 after two years of marriage, while her union with childhood friend Jason Alexander was annulled in January 2004 - has been dating agent Jason Trawick for two years and says she`s very happy with him and would consider tying the knot if he proposed. When asked if she has plans to marry, Britney told Us Weekly magazine: "Maybe. Never say never! "We have such a great time together! He makes me laugh, and we are so comfortable being ourselves. "I`ve never been happier." Britney - who has two sons, Sean Preston, five, and four-year-old Jayden James, with Kevin - has previously spoken about Jason, saying she loved how grounded her kept her. She said: "We`re really normal. We just like to watch movies. We work out a lot. We love to work out. We do stuff together like that. We take walks." The 29-year-old star recently revealed how her family life comes first and schedules her work around it. She explained: "I`m usually pretty busy when I`m not working. I have two children, so I usually get them up in the morning, and I`m usually at the gym, and I help cook dinner sometimes ... a lot of the stuff that I do I do early in the morning when my boys are at school."
